Answer:
area of shaded portion of figure = 76.24 cm²
Step-by-step explanation:
find the area of the circle, a 60° segment of the circle, and an equilateral triangle with sides of 5 cm:
area of circle = πr² = (3.14)(5²) = 78.5 cm²
area of 60° segment of circle = 78.5/6 = 13.08 cm²
area of triangle = 1/2(4.33)(5) = 10.82 cm²
The shaded area will be:
full circle area - (60° segment - triangle) = 78.5 - 13.08 + 10.82 = 76.24 cm²
< 2 + < 3 + 90 = 180
< 2 = x + 8
< 3 = 2x + 7
x + 8 + 2x + 7 + 90 = 180
3x + 105 = 180
3x = 180 - 105
3x = 75
x = 75/3
x = 25
< 2 = x + 8 = 25 + 8 = 33 <==== answer is D
< 3 = 2x + 7 = 2(25) + 7 = 50 + 7 = 57
