Since you haven't mentioned any specific name for the ray, let it be ray OC ( where O is the point on line AB and C is the given ray.)

So Angle AOC is a straight angle.

Also, the measure of a straight angle is 180°

angle AOC+ angle BOC = 180° ..(1)

Given:

Angle AOC = (3x+20)°

Angle BOC = (4x-36)°

to find:

value of x.

solution:

3x + 20 + 4x - 36 = 180° ( from equation 1)

7x - 16 = 180°

7x = 196

x = 196/7

x = 28.

Hence the value of x is 28.
