Answer:
You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.
Step-by-step explanation:
The one wall would be 13 feet long.
13+13+13+13= 52 feet.
Area of the small circle =
r
= 3.14 x 7
= 153.86
Area of the big circle =
R
=3.14 x 14
= 615.44
The shaded area = area of the big circle - area of 2 small circle = 615.44-2x153.84≅308
The answer is 308
70÷6=11.66666667 this is the exact answer
