Question

In a quadrilateral, if two angles are complementary and other two angles are in ratio of 4:5.Find the measure of these two angles.

Answer 1

If two angles are supplementary then the other two will also be supplementary...
4x+5x=180
9x=180
x=20
4x=4*20=80
5x=5*20=100

Answer 2

Answer:

Sum of all the interior angles of quadrilateral is 360°

Two angles=90 (given)

Remaining 2 angles= 4:5

Let another two angles = 4x and 5x

4x+5x=180°

9x= 180

x= 180

9

x =20

4x=80

5x=100

Please make this answer brilliant
