Can someone help me?

Exterior angle = Sum of its interior opposite angles ( exterior angle property )

Which means :-

Then :-

1) ∠ 7x - 1

= 7 × 10 - 1

= 70 - 1

2) ∠14x - 8

= 14 × 10 - 8

= 140 - 8

As the sum of interior opposite angles of this triangle is equivalent to the value of the exterior angle (69+63=132), we can conclude that we have found out the correct value of x .

Therefore , the value of x = 10 .
