Answer 1

70+50+x=180. 180-120=60

Answer 2

Step-by-step explanation:

As you can see that x is the third part of the Straight Angle so we can understand that all the three parts make sum of 180 degrees.

78° + 50° + x = 180°

128° + x = 180°

x = 180° - 128°

x = 52°

That means value of x is 52°
