Please Help Me I Really Need It Geometry?

Answers

Answer 1

Answer:

height= 30 area= 2160

Step-by-step explanation:

I don't think this is even right, but since a triangle adds up to 180, subtract the 72 and both 39's from 180. that should give you 30, the missing number (the height)

Then, to find area the formula is a=b*h

You already have the base in the image and you already calculated the height

Again, I don't know if this is right. It's not the same as how I do it here

Answer 2

Answer:

h = 15, A = 540

Step-by-step explanation:

Since the 2 legs are congruent then h is a perpendicular bisector, dividing the triangle into 2 right triangles.

Using Pythagoras' identity on one of the right triangles

with leg 72 ÷ 2 = 36 and hypotenuse = 39

h² + 36² = 39²

h² + 1296 = 1521 ( subtract 1296 from both sides )

h² = 225 ( take square root of both sides )

h = [tex]\sqrt{225}[/tex] = 15

Then

A = [tex]\frac{1}{2}[/tex] × 72 × 15 = 36 × 15 = 540 mi²

How do you find the circumference of a circle? Please include an example if you’d like.

Answers

Answer:

Step-by-step explanation:

Plug the given value of the diameter into the formula and solve.[2]

Example problem: You have a circle tub with a diameter of 8 feet, and you want to build a white fence that creates a 6-foot wide space around the tub. To find the circumference of the fence that has to be created, you should first find the diameter of the tub and the fence which will be 8 feet + 6 feet + 6 feet, which will account for the entire diameter of the tub and fence. The diameter is 8 + 6 + 6, or 20 feet. Now plug it into the formula, plug π into your calculator for its numerical value, and solve for the circumference:

C = πd

C = π x 20

C = 62.8 feet

Chris has 7/8 yards of purple ribbon and one whole one over 6 yards of ribbon Chris has a total of three holes to over 3 yards of ribbon how many yards of Chris's ribbon are neither purple nor green

Answers

Complete question :

Chris has 7/8 yards of purple ribbon and 1 1/6 yards of green ribbon. Chris has a total of 3 2/3 yards of ribbon. How many yards of Chris's ribbon are neither purple nor green.

Answer:

1.625 yards

Step-by-step explanation:

Purple ribbon = 7/8 yards

Green ribbon = 1 1/6 yards = 7/6 yards

Total ribbon = 3 2/3 yards = 11/3 yards

Ribbon that is neither purple nor green :

Total ribbon - (green + purple ribbon)

7/8 - (7/6 + 7/8)

11/3 - (28 + 21) / 24

11/3 - 49/24

= 1.625 yards

The height, in inches, of each of three boys is 54.0, 48.5, and 46.0, respectively. The height of the fourth boy is denoted by h inches. The average height, A, of the 4 boys can be expressed as a function of h in the form:
A(h) = (c + h)/d

1. What is the domain for the function A(h)?
2. The average height of all 4 boys is 50.5 inches. What is the height of the fourth boy?

Answers

Answer:

53.5

Step-by-step explanation:

c = the height of the first 3 boys.

c = 54 + 48.5 + 46

c = 148.5

Now you add a fourth boy. His height is h.

A(h)= (c + h)/d      

d = the total number of boys which is 4.

The new average is 50.5

A = (c + h)/d

50.5 = (148.5 + h) / 4            Multiply both sides by 4

202 = 148.5 + h                    Now subtract 148.5 from both sides

202 - 148.5 = h

h = 53.5

A water tank holds 657 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 876 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the two tanks be the same?

Answers

Sometimes setting up the equation is the hardest part. Starting gallons minus (leaking gallons times number of leaking weeks) equal to the other tank, same setup.

657 - 4w = 876 - 7w
3w = 219
w = 73

Checking the math:

657 - 4(73) = 365
876 - 7(73) = 365

73 weeks

Find AC please, help is very much appreciated.

Answers

Answer:

AC ≈ 67.9

Step-by-step explanation:

15² = 9 (3x + 1 + 9)

225 = 9 (3x + 10)

225 = 27x + 90

135 = 27x

x ≈ 19.29

AC = (3x + 1 + 9)

AC = 3 (19.2857...) + 1 + 9

AC = 57.857... + 1 + 9

AC =  57.857... + 10

Lets write an equation for this :)

So, the sum of -3 times a number and 0.3

This would be : -3x +0.3

Is at most, 6.3

so, it is equal to, or less than 6.3

-3x +0.3 < 6.3

Answer:

105

Step-by-step explanation:

Hello There!

(Let x = angle T)

if you didn't know an exterior angle of a triangle is equal to its two opposite interior angles

So basically

155 (being the exterior angle) is equal to 50 + x (being the opposite interior angles)

so x = 155 - 50

155 - 50 = 105

so we can conclude that x (angle T) equals 105

Answer:

105 degrees

Step-by-step explanation:

The angle measure of the exterior angle is equal to the sum of the two nonadjacent interior angles (angle V and angle T).

155 - 50 = 105
