Question

Find the value of x in the following figures

Answer 1

Answer:

If AB and AC is equal in size so angel

ACB =ABC=(180-50)/2=65°

so,x=(180-65)=115°

Answer 2

Answer:

Given, a ΔABC is isosceles.

∠A=50°

∠B=∠C (Isosceles triangle)

Let us take ∠B=y

∠A+∠B+∠C=180°(Angle sum property)

50°+y+y=180°

2y=180°-50°

y=130°/2

y=65°

∠A+∠B=∠ACD (Exterior angle property)

50°+65°=x

x=115°
