Answer:

34

Step-by-step explanation

Sine and cosine of complementary angles. therefore

(2x + 2) + (3x + 8) = 90

x = 16

then,

2(16) + 2 → x = 34

3(16) + 8 → x = 56

which means

β = 34

Find the area of the shaded regions:
Crank

First, we'll find the area of the large section, including the smaller section that is white.

Area of a circle: pi x r^2

A = pi x 7^2

A = 49pi x 120/360

A = 49/3 pi cm^2

Now, we'll find the area of the small section.

A = pi x 3^2

A = 9 pi x 120/360

A = 3pi cm^2

All that's left to do now is subtract.

49/3 pi - 3 pi

40/3 pi cm^2

(or 13 1/3 = 13.33 cm^2)

Hope this helps!
