Question

a playground is in the shape of a convex quadrilateral to office interior angle are right angles if the remaining two angles are in the ratio 4 ratio 5 find the measure of all the interior angles​

Answer 1

Answer:

4x+5x=180

9x=180

x=180/9

x=20

so, first angle =4*20=80 degre

second angle =5*20=100 degre
