Answer:
The value of x is 13
Step-by-step 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
