Answer:
Multiply 180 degrees by (n minus 2)
Step-by-step explanation:
Number of sides in the polygon = n
Polygons have sides 3, 4, 5, 6.....
Polygon with 3 sides is a triangle
Polygon with 4 sides is a quadrilateral
Sum of it's Interior angles = (n-2) × 180°
For a 3 sided polygon
Sum of it's Interior angles = (n-2) × 180°
= (3 - 2) × 180°
= 1 × 180°
= 180°
For a 4 sided polygon
Sum of it's Interior angles = (n-2) × 180°
= (4 - 2) × 180°
= 2 × 180°
= 360°

Step-by-step explanation:
cos F = HF/FG
cos 52° = x/(4.3)
0.6 = x/4.3
=> x = 4.3 × 0.6
x = 2.58
so the length of HF = 2.58 = 2.6 ft

The equation of line CD is (y−3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD? (4 points) negative 1 over 2 −2 2 1 over 2
Answer:
answer 1/2
Step-by-step explanation:
y-3=-2(x-4)
y-3=-2x+8
y=-2x+11
y=mx+c
m= slope which is -2
because it perpendicular It became 1/2

In a competative exam of 40 questions plus three months is awarded for a correct answer and minus one for every correct answer to find the total score for student had 11 wrong answers in his attempt of all questions.
Answer:
76
Step-by-step explanation:
n a competitive exam of 40 questions, +3 is awarded for a correct answer and -1 for every wrong answer. Find the total score if a student had 11 wrong answers in his attempt of all questions.
Answers gotten wrong = 11
answers gotten right = 40 - 11 = 29
total score = (point for correct answer x number of correct answer) + (point for wrong answer x number of wrong answer)
(+3 x 29) + (-1 x 11) = 76

An angle measures 62.6° less than the measure of its complementary angle. What is the
measure of each angle?
and
Answer:
The angles are 13.7 degrees and 76.3 degrees
Step-by-step explanation:
Let the complementary angle be x
When two angles are complementary, they add up to 90 degrees
So if one is x , the other would be (x-62.6) as stated by the question
so, adding this two will give 90 degrees
We have this as;
x + x -62.6 = 90
2x = 90 + 62.6
2x = 152.6
x = 152.6/2
x = 76.3
The other angle will be;
76.3 -62.6 = 13.7

Whats the value of b?
Answer:
b = 5
Step-by-step explanation:
This triangle is a 30 - 60 - 90 special right triangle
As you can see in the image provided below the longer leg is equal to the short leg times √3
This means that the short leg is equal to the long leg divided by √3
Thus, b = [tex]\frac{5\sqrt{3} }{\sqrt{3} }[/tex] which is equivalent to 5

Drag each situation to show whether it can be modeled using a linear or an exponential function. If the situation cannot be modeled with either function type, drag it into the container labeled Neither.
Answer: the savings account one is linear, the enrollment of students is linear, the investment is exponential as well as the cars value, the speed of the truck is neither (not fully sure) and the temperature outside is linear
Step-by-step explanation: linear means in a straight line without curves meaning if the question mentions percentages it’s automatically not linear as percentages tend to curve. Exponential means it curves which has direct connections to percentages and getting multiplied by

Find the measure of the missing angles.
g=
h=
m=
k=
(NO FILES) YOU WILL GET MARKED BRAINLY :)!!
Answer:
g. 92*
h. 88*
m. 89*
k. 91*
Step-by-step explanation:
To find h and m: All of the angles on a straight line added up equals 180*. So if there are two angles, the sum of them must equal 180* (angle A + angle B = 180*)
So in this case we have angle h + 92* = 180* using algebra, we subtract 92 from both sides and we get angle h = 88*
If you want to check, add 92 + 88 = 180.
Also angle m + 91* = 180*. Same thing as above, subtract 91 from both sides and we get angle m = 89*
If you want to check, add 91 + 89 = 180.
When you have two straight lines intersecting (crossing), the opposing angles at that crossing are going to be equal. So in this case angle g is opposite from the anbgle that we know is 92*, so angle g is also 92*. Same thing for angle k, we know the angle opposite angle k is 91*, so we know that angle k is also 91*.

Answer:
The answer to your question is 26.75
Step-by-step explanation:
Top triangle = 3.5 x 9 = 31.5. Since it is a triangle, it has to be split in half (15.75).
Bottom left triangle = 2 x 2 = 4. Since this is also a triangle: 4 split in half is 2.
Bottom square = 2 x 2 = 4.
Bottom right triangle = 5 x 2 = 10. Since it is a triangle, 10 / 2 = 5.
After you get the area of each individual shape, add them together to get 26.75.

Answer:
Only the second one(B)
Step-by-step explanation:
Only the second one had a right angle of 90 degrees.
Below are the attachments of the triangle drawings.
Hope this helps!
Answer:
2, 6, and 7.
Step-by-step explanation:
In a right triangle, the hypotenuse (longest side of the triangle) squared is equal to the sum of the other sides squared.
So for the second triangle, add 36 squared to 15 squared. The result is 1521. Compare that to the hypotenuse (39) squared. The second triangle is a right triangle because the hypotenuse squared is also 1521. I did this with each triangle and the 2nd, 6th, and 7th were right triangles.

2 1/5
Step-by-step explanation:
Because we are finding the area we are multiplying and the formal is L x W = Area so the Length is 3 1/2 and the width is 5/7 so we multiply them and we get: 2.5
3 1/2 x 5/7 = 2.5 let make it a mixed number 5/2 let simplify it now 5 divided by 2 = 2 1/5

5(y+25)=−13 what is y
Answer:
y = -27.6
Step-by-step explanation:
To solve for y, you need to isolate the variable on one side of the equation. [tex]5(y+25)=-13[/tex] ⇒ [tex]y + 25 = -2.6[/tex] ⇒ [tex]y = -27.6[/tex].
Answer:
-27.6
Step-by-step explanation:
[tex]5(y + 25) = -13[/tex]
First, distribute the problem.
[tex]5y + 125 = -13[/tex]
Secondly, subtract 125 from -13 and 125.
[tex]125 - 125 = 0[/tex]
[tex]-13 - 125 = -138[/tex]
Now, we are left with 5y = -138.
Lastly, we divide -138 by 5.
[tex]-138 / 5 = -27.6[/tex]
Therefore, y is -27.6.

[tex]\text{State Income Tax Rate: }6.65\%, \\\text{Deduction: }\$7,702.03[/tex]
Answer:
State income tax: [tex]6.65\%[/tex]
Step-by-step explanation:
Based on the interface, it seems like you have chosen lawyer as a career with the given salary of $115,820.
The chart given for state income tax is broken into two categories:
$21,400-$80,650 => 6.45%
$80,651-$215,400 => 6.65%
Since the chosen career's salary is $115,820, the career falls into the second range of 6.65% state income tax.
The deduction is simply the amount of money taxed. For a 6.65% state income tax, the deduction can be found from:
[tex]115,820\cdot 0.0665=\boxed{\$7,702.03}[/tex]
The vertex angle of an isosceles triangle is three times the measure of either base angle. Find the area if the measure of the congruent sides are 14 in
Answer:
[tex]Area = 93.21in^2[/tex]
Step-by-step explanation:
Given
[tex]\theta \to[/tex] vertex angle
[tex]\alpha \to[/tex] base angle
[tex]\theta = 3\alpha[/tex]
[tex]l = 14in[/tex] -- congruent sides
Required
The area of the triangle
First, calculate the angles
[tex]\theta + \alpha + \alpha = 180^o[/tex] ----- angles in an isosceles triangle
Substitute [tex]\theta = 3\alpha[/tex]
[tex]3\alpha + \alpha + \alpha = 180^o[/tex]
[tex]5\alpha = 180^o[/tex]
Divide both sides by 5
[tex]\alpha = 36^o[/tex]
Recall that: [tex]\theta = 3\alpha[/tex]
[tex]\theta = 3 * 36^o[/tex]
[tex]\theta = 108^o[/tex]
The area is then calculated as:
[tex]Area = \frac{1}{2}l^2 \sin(\theta)[/tex]
[tex]Area = \frac{1}{2}*14^2 \sin(108^o)[/tex]
[tex]Area = \frac{1}{2}*196 *0.9511[/tex]
[tex]Area = 93.21in^2[/tex]
