Question

An interior angle of a parallelogram is 24 degree greater than double of the measure of the exterior angle adjacent to it.Determine the measure of the interior angle?

Answer 1

128

Explanation:

If the exterior angle is `x`, then the interior angle is `2x+24`
Together they total `180^@`

So `x+2x+24=180`

`3x+24=180`

`3x=156`

`x=52`

`2 xx 52+24=104+24=128`
