Question

Two adjacent angles of a parallelogram are (6x-9) and (13x+18) Find the ratio of these angles .give solution also please​

Answer 1

Answer:

1:3

Step-by-step explanation:

In a parallelogram, sum of adjacent sides is 180°

So,

$6x - 9 + 13x + 18 = 180 \\ 19x + 9 = 180 \\ 19x = 171 \\ x = 9$

Put this x - value in the given angles

$6(9) - 9 \\ 54 - 9 \\ = 45$

Other angle is

$13(9) + 18 \\ 117 + 18 \\ = 135$

The ratio of the two angles is

$\frac{45}{135} = \frac{1}{3}$

The ratio is 1:3.
