The measures of the angles of a triangle are shown in the figure below. Solve for x.
(2x+12)°
42°
Answers
-12. = -12
2x = 30
Divide by 2 = divided by 2
X= 15
That how you solve it
Explanation: So we know that when you add all angles together of a triangle it has to equal 180° and we know that one of the angles is 90° another is 42° and the last one is (2x+12)° so our equation would be
180=90+42+(2x+12)
add all the numbers that we can and get
180=2x+144
now subtract 144 from both sides so we could have the 2x by itself
36=2x
now to find the x we need to get rid of the 2 so we divide by 2 on both sides and get
18=x

Answers
Answer:
x = 33 degrees
Step-by-step explanation:
Angle ABC = BDA because they are alternate interior angles.
So:
Angle BDA = 42 degrees
x = 180 - 105 - 42
x = 33 degrees
The sum of two opposite angles of a quadrilateral is 280°. The other two angles are equal. Find the measure of the equal angles. (Please)

40° each
Step-by-step explanation:
The interior angles of a quadrilateral add up to 360°.
360° - 280° = 80°/2 = 40°
How many cuts do you need to cut a stick into:
6 parts?
11 parts?
x parts?
Answers
Answer:
5,10,1.
Step-by-step explanation:
I'm not sure about the last one but I tried. hope this helped.
Answer:
5 cuts, 10 cuts, and for the last one it is an equation.
x parts - 1 = amount of cuts for x parts.
Step-by-step explanation:
I cannot upload an image but I can represent a half image/text to show how to find out the number of cuts.
Here is a "stick" that has been cut into 6 parts.
_ _ _ _ _ _
If you count the number of cuts in the "stick", you can tell it is 5 cuts, which is one less than 6. Let's try cutting a stick into 11 parts now.
_ _ _ _ _ _ _ _ _ _ _
As you can see, there are 10 cuts in the "stick". Therefore, you can use the equation, x-1 = amount of cuts, where x represents the number of parts the stick has been cut into.
The final answer:
5 cuts
10 cuts
x-1

Answer:
y=-2x-3
Step-by-step explanation:
The set up is always y=mx+b. You have to find m (m is slope) and b (b is y-axis). Since the line goes down, it has a negative slope. From the first point to the second, it goes down 4 and over 2. If you divide 4/2, you get 2 for the slope. The y-axis is just where the point meets the y-axis line and in this example, it meets at -3 so that is your b value.

So,
[tex]\sf (x_{1},y_{1}) = (2,2)\\\\(x_{2},y_{2}) = (0,-3)[/tex]
Hence,
[tex]\sf Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\\\Slope = \frac{-3-2}{0-2} \\\\Slope = \frac{-5}{-2} \\\\Slope = \frac{5}{2} \\\\\rule[225]{225}{2}[/tex]
