Mathematics
1 answer:
Anna [14]3 years ago
7 0

Answer:

angle 1 should equal to 54.

angle 2 should equal to 126.

Step-by-step explanation:

2x - 8 + 4x + 2 = 180

2x + 4x - 8 + 2 = 180

6x - 6 = 180

6x - 6 + 6 = 180 + 6

6x = 186

6x ÷ 6 = 186 ÷ 6

x = 31

---------------------------------------------

2x - 8 = A1

2(31) - 8 = A1

62 - 8 = A1

54 = A1

-----------------------------------------------

4x + 2 = A2

4(31) + 2 = A2

124 + 2 = A2

126 = A2

Answer:

67.5 ft^2

Step-by-step explanation:

First find the area of the circle.

A = pi r^2

A = pi (8)^2

A = 64pi

There are 360 degrees in a circle

The shaded area has 121 degrees

The fraction is 121/360

The fraction shaded is 121/360

The fraction of the circle is the same as the area

121/360 A = 121/360 * 64 pi

area shaded = 67.54488889

To the nearest tenth

area shaded = 67.5
