☞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.
