Pls help if you can,,,,

Step-by-step explanation:

All the angles in a construction like this one are either 7x or 11x. In this case the acute angle is 7x and the obtuse angle  is 11x

11x + 7x = 180

18 x = 180

x = 10

So 7x = 7 * 10 = 70

11 x  = 11 * 10 = 110

Part C

The relationship is that the acute angle + the obtuse one = 180
