If the sum and difference of two angles are 135° and $$\frac{\pi }{{12}}$$ respectively, then the value of the angles in degree measure are:
A. 70°, 65°
B. 75°, 60°
C. 45°, 90°
D. 80°, 55°
Answer: Option B
Solution (By Examveda Team)
∠A + ∠B = 135° . . . . . . . . (i)∠A - ∠B = $$\frac{\pi }{{12}}$$ = 15° . . . . . . . . (ii)
Adding both equation
2∠A = 150°
⇒ ∠A = 75°
∠B = 60°
