Answer:
B. 60°
Step-by-step explanation:
Well you see that VUY is 40° and that is you were to flip that over into the VUW angle, it will be twice the size of 40°. I'm not saying its addition, but this is my opinion.
The final interior angle is 127<span>°. Pentagons' interior angles add up to 540, so you add the ones you know together, subtract the big number from 540, and you have your answer. </span>
When brackets are used in a expression its most likely there and there's parenthesis inside of the brackets. Hope this helps. :|
