Answer:

Explanation:

Let the fourth angle be x.

We know that,

Sum of all four angles of a quadrilateral = 360

Therefore,

150+35+70+x = 360

210+x = 360

x = 360-210

x = 150

Hence , the fourth angle is 150

Let the fourth angle be x

=> 105° + 35° + 70° + x = 360°

=> 210° + x = 360°

=> x = 360 - 210

=> x = 150°
