Given:

Consider the below figure attached with this equation.

Quadrilateral QRST is a parallelogram.

To find:

The value of x.

Solution:

We know that the sum of two consecutive interior angles of a parallelogram is 180 degrees because they are supplementary angles.

In parallelogram QRST,

m\angle Q+m\angle T=180^\circ

(3x+5)^\circ+(9x-17)^\circ=180^\circ

(12x-12)^\circ=180^\circ

On comparing both sides, we get

12x-12=180

12x=180+12

12x=192

Divide both sides by 12.

x=\dfrac{192}{12}

x=16

Therefore, the value of x is 16.
