Let the other two equal angles be x
Since it is given that the angles are of a quadrilateral, their sum should be 360° (angle sum property of a quadrilateral)
=> 70 + 80 + x + x = 360°
=> 150 + 2x = 360°
=> 2x = 360 - 150
=> 2x = 210°
=> x = 210/2
=> x = 105°
Your answer is 105°
Hope it helps dear friend ☺️

70+80=150degree in quadrilateral the sum of all angles is 360degree so the angles will be 360-150=210degree but as the two angles are equal se 210 /2=105degree both.......
