Solution
360° - 2x90° = 180°
the ratio of 2:3. Find the measure of the third and fourth angle.
Two angles of a quadrilateral are of 90°each. The third and fourth angle are
Two angles of the quadrilateral are equal to 90° each.
The measure of the remaining two angles
The ratio between the third and the fourth angle = 2 : 3
Let the angles be of 2x and 3x
2x + 3x = 180°
5x = 180°
180°
= 36°
5
Third angle = 2 x 36° = 72°
Fourth angle = 3 X 36° = 108°
