Answer: 45°
Step-by-step explanation:
Given that :
∠A=5x−15°---(1)
∠B=2x+21°----(2)
Equating
∠A = ∠B
(5x−15)° = (2x+21)°
5x - 15 = 2x + 21
Collecting like terms
5x - 2x = 21 + 15
3x = 36
x = 12
Substitute x = 12 in either angle A or B since both are congruent
∠A=(5x−15)°
∠A = (5(12) - 15)°
∠A = (60 - 15)°
∠A = 45°
∠A = ∠B = 45°
