Answer 1

QUESTION:-

The adjacent angles of a parallelogram are in the ratio 4:5. Find all the angles of a parallelogram.

ANSWER:-

The adjacent angles of a parallelogram, sum is 180°.

so, 4:5 = 4x ,5x

$4x + 5x = 180 \\ \\ 9x = 180 \\ \\ x = \frac{180}{9} \\ \\ x = 20 \\ \\ 4x = 4(20) = 80 \\ \\ 5x = 5(20) = 100$
