HEY BUDDY I HOPE IT HELPS YOU

Step-by-step explanation:

Q. Find the value of x.

Solution:

In ∆ABC,

Angle A + Angle B + Angle C = 180° [ Area of a triangle ]

x° + ( 2x + 2 )° + ( 2x - 7 )° = 180°

x + 2x + 2 + 2x - 7 = 180

5x - 5 = 180

5 ( x - 5 ) = 180

x - 5 = 180 / 5

x - 5 = 36

Therefore, x = 36 - 5 = 31

Ans. The value of x is 31.
