Answer:
m∠H = 44°
Step-by-step explanation:
Consecutive angles of a parallelogram are supplementary. So,
∠H and ∠G are supplementary
4x + 16 + 2x - 16 = 180
6x = 180
x = 30
m∠H = 2x - 16 = 2(30) - 16 = 60 - 16 = 44°
The standard equation for circumference
CC= 2pi(D/2)
plug in variables
CC=2pi(5656/2)
so the equation would be
CC=(2)(pi)(2828)
