Answer:
∠a = 42.5°
∠b = 87°
∠c = 174°
∠d = 90°
∠f = 131°
Step-by-step explanation:
∠a = 85°/2 = 42.5°
∠b = 360° -110° - 76° = 174°/2 = 87°
∠c = 360° -110° - 76° = 174°
∠d = 90°
∠f = 360° - 101° - (64° x 2) = 131°
If the width is w and the length is l, then 2w+2l=perimeter=34=2*6.5+2l=13+2l. Subtracting 13 from both sides, we get 21=2l and by dividing both sides by 2 we get 10.5
