Question

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

Answer 1

Add 3x and 2x together to get 5x. Then do 88+108-6 and you get 190. To find x now all you have to do is use 5x+190=360 to get x.
360 -190= 170 now you have 5x=170 divide 170/5 and that will give u the value of x.

Answer 2

You answer should be 34 Degrees.
