Answer:

This is simple. The answer is 60 for the first, and the second one I believe is 85

Step-by-step explanation:

Since we are dealing with quadrilaterals, we know that all the inside angles add up to 360. In your isosceles trap. the top two angles are the same, and the bottom two are the same. So, we can do 120*2=240 for the top angles, and then subtract that from 360. 360-240=120. 120/2=60

Hope it helps
