Answer:
Missing angle = 135°
Step-by-step explanation:
Given:
Pentagon shape
Number of right angle = 3
Remain two angles are equal
Computation:
Sum of Pentagon angles = 540°
So,
90 + 90 + 90 + a +a = 540
270 + 2a = 540
a = 135°
Missing angle = 135°
Answer:
43 cm
Step-by-step explanation:
C = 2 * pi *r
86pi = 2 * pi *r
Canceling pi from each side
86 = 2r
Divide by 2
86/2 =2r/2
43 =r
