Answers

Answer:

Step-by-step explanation:

Each internal angle in a regular pentagon = 180(n - 2) / 5 where n = 5

so < BAE =  540/5 = 108 degrees.

Triangle BAE is isosceles  so

m < ABE =( 180 - 108 )/ 2

= 36 degrees.

The measure of an angle is 77°. What is the measure of its complementary angle?

Answers

Answer:

13º

Step-by-step explanation:

Complementary angles are angles that add up to 90º. So, subtract 77 from 90, and you get 13.

63 degrees, if that angle is 72 that means the other must be 54 (add to 180), and if that angle on the other triangle is 54, the others must be 63 (add to 180).

Answers

ANSWER:
d. x = 15, y= 15√3

EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have

We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15

We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.

x = 15
y = 15√3

Sorry if I explained it too thoroughly but I’ll be glad to answer any questions or clarifications

Harold cut 1812 inches off a rope that was 60 inches long. How is the length of the remaining rope in inches written in decimal form

Answers

Answer:

0.42

Step-by-step explanation:

The computation of the length of the remaining rope in inches is shown below:

Length Remaining = Length - the piece he cut off

Length Remaining = 60 - 18

60 - 18 = 42

To turn 42 into a decimal, you have to divide by 100 ↓

42 ÷ 100 = 0.42

The length of rope remaining is 0.42 inches long

Answers

Answer:

3.81 inches

Step-by-step explanation:

πr² + 100 = π(r+3)²

divide by π and simplify:

r² + (100/π) = r² + 6r + 9

100/π = r² + 6r + 9

31.8309886184 - 9 = r² +6r

r² = 6r - 22.8309886184

0 = 6r - 22.8309886184

22.8309886184 = 6r

divide by 6:

3.80516476973 ≈ 3.81 inches

What is the approximate area of this figure?

Use 3.14 for pi.

Enter your answer in the box. Round only your final answer to the nearest whole number.

Answers

Answer:

157 in²

Step-by-step explanation:

The area of the shape is the sum of three sections

1. Rectangle

A = 5*14 = 70 in²

2. Bigger semicircle

A = 1/2π(14/2)² = 76.96 ≈ 77 in² (rounded)

3. Smaller semicircle

A = 1/2π(5/2)² = 9.8174 ≈ 10 in² (rounded)

Total area:

70 + 77 + 10 = 157 in²

answer:

157 inches²

step-by-step explanation:

we have to break this down into parts and find the area of each part and then add them up so we have the area for the whole thing

rectangle:

5 X 14 = 70 inches²

big semicircle:

solve this like a simple circle and then divide by 2 since this is half

area = πr²

insert what we know from the question

area = (3.14)(7)²

the radius would be seven because as you can see the length of a side of the rectangle is 14 and this is also the diameter of the circle since they are attached and share itthe radius is half of the diameter so we get 7

area = 3.14(49)

        = 153.86 inches²

now divide this by 2 since it is semicircle

153.86 / 2 = 76.93 inches²

small semicircle:

area = (3.14)(2.5)²

i followed the same method as last, except the numbers are different

area = 3.14(6.25)

        = 19.625 inches²

now divide by 2

19.625 / 2 = 9.8125 inches²

finally, add up all the separate areas you got

70 inches² + 76.93 inches² + 9.8125 inches²

= 156.7425 inches²

= 157 inches²
