Answer:
7. 52
8. 20
Explanation:
all angles add up to 180
7. since there is a line passing through all the sides we can assume it the sides are the same length as well as the angles. since 180 divided by 3 angle is 180, you subtract 8 from 60 giving you 52
8. since all lengths are 5, that means all angles are the same as well. since there are 3 angles, you need 3 numbers that add up to 180 which is 60. 3 multiplied by 20 is 60 which is your answer
