Answer:
A. ∵AB = AC
SO, ∠B = ∠C
∠C = x = 80°
B. ∵ LN = LM
SO, ∠N = ∠M
∠M = 20°
x+20°+20° = 180°
x = 180°-40° = 140°
C. ∵ PQ =PR
SO, ∠Q = ∠R
∠Q = x°
x°+x°+50° = 180°
2x +50° = 180°
2x = 130°
x = 65°
D. ∵QR = PR
SO, ∠Q = ∠P
∠Q = 59°
x+59°+59° = 180°
x = 180°-118° = 62°
also ∠PRS = 180°-62° = 118°
y+118°+32° = 180°
y = 180°-150° = 30°
E. ∵AE = AD
∠D = 63°
∠DAE = 180°-63°-63° = 180°-126° = 54°
∠CAB = 54° [voa]
∵AB = AC
∠B = x
x+x+54° = 180°
2x = 180°-54° = 126°
x = 63°
