1.	1. Three angles of a quadrilateral are 75°, 90° and 75°. Find the measure ofthe fourth angle.
Answer» As we all know that the sum of all interior angles of a quadrilateral =360° So , let us take the 4th angle as X.. Then:- 75°+90°+75°+X=360°240°+X=360°X = 360°-240°X= 120° so the 4th angle will be 120°

1. Three angles of a quadrilateral are 75°, 90° and 75°. Find the measure ofthe fourth angle.

Answer»

As we all know that the sum of all interior angles of a quadrilateral =360° So , let us take the 4th angle as X..

Then:- 75°+90°+75°+X=360°240°+X=360°X = 360°-240°X= 120°

so the 4th angle will be 120°
