Question

In figure AE is the bisector of angle A, AD is perpendicular to BC. Find x

Answer 1

From ∆abc Angle a +b+c = 180 [angle sum property] = 2x+65+30 =180 => 2x = 180-95 => x = 85/2 = 42.5

Answer 2

In abc
a+b+c = 180
(a=x+x)
So,
(X+x) + b + c = 180
2x + 65 + 30 = 180
From here,
Find x

So easy to understand
