Answer:
6. Should be 10
8. X=120 degrees
Step-by-step explanation:
6. If you add 5+2+3, it equals 10
8. two of the sides are right angles. Together, they add up to be 180 degrees. the other angle is 60 degrees. 180 and 60 together are 240. Then, subtract from 360 since your shape is a quadrilateral. 360-240=120
