In an isosceles triangle, if the unequal angle is twice the sum of the equal angles, then each equal angle is

A. 120°

B. 60°

C. 30°

D. 90°

Answer: Option C

Solution(By Examveda Team)

According to question,
Given :

AB = AC
y = 2(x + x)
y = 4x
∴ x + x + y = 180°
2x + 4x = 180°
6x = 180°
x = $$\frac{{{{180}^ \circ }}}{6}$$
x = 30°
