How do I find x In these two problems?

#1: 146 degrees #2: 111 degrees (don't forget to add the right angle, which is 90 degrees)

Step-by-step explanation:

The angles of a heptagon (a shape with 7 sides) are supposed to add up to 900 degrees, so just add up all the sides that you know and subtract it from 900 and you will have x! Do the same thing with the second one, except is is a hexagon and all the angles should add up to 720 degrees. So add up all the sides you know and subtract from 720 to get x.

17   x 256=4352
