Solution:-

angle 1 + angle 2 + angle 3 + angle 4 = 360(the sum of angles of the quadrilateral is 360 degree.)

Let 4th angle be x.

_____________________

105 degree + 35 degree + 70 degree + x = 360 degree

210 degree + x = 360 degree

4rth angle =x = 360 degree - 210 degree

4th angle = 150 degree .

So, fourth angle is 150 degree.
