This is a quadrilateral, so the sum of interior angle measures, like a rectangle or square ( who’s interior angle measures are4 x 90) —— is 360
So ...
E + 89 + 130 + 90 = 360
E + 309 = 360
- 309 - 309
E = 51 degrees
Step-by-step explanation:
n2+5=21
n2 =21-5
n2 = 16
n =16/2=8
Divide 150 by 50 to get 3
