Step-by-step explanation:

We know that,

The sum of all angles of a triangle is 180°.

So,

Here,

(x - 40) + (x - 20) + ( \frac{x}{2 - 10} ) = 180

2x - 60 -  \frac{x}{8}  = 180

multiplying \: both \: sides \: by \: 8

15x - 480 = 1440

15x = 960

x = 960 \div 15

x=64°

I hope it will help you....
