Answer: C) 60</h3>
Explanation:
There are n = 6 sides in a regular hexagon, so each exterior angle is E = 360/n = 360/6 = 60
The rule E = 360/n only works for regular polygons with n sides, which means the polygons must have all sides the same length and all angles the same value.

Answer:
151.4496 cm²
Step-by-step explanation:
The area of a trapezoid is found using the formula ...
A = (1/2)(b1 +b2)h
where b1 and b2 are the lengths of the parallel bases and h is the distance between them. Fill in the numbers and do the arithmetic.
A = (1/2)(22.2 cm + 8.52 cm)(9.86 cm) = 151.4496 cm²
