Question

Isosceles triangle ABC has vertex angle A=4x-6 and angle B=5x+2 what is the value of X

Answer 1

The value of x is 13

Explanation:

Given angles of triangle ABC are

Angle A = 4x-6

Angle B = 5x+2

Angle C = 5x+2

To find the value of x:

From property of triangle,

Angle A + Angle B + Angle C = 180

(4x-6) + (5x+2) + (5x+2) = 180

(4x+5x+5x) +(-6+2+2)=180

14x+(-2)=180

14x=182

x=13

Thus, The value of x is 13
