Hi there!

In order to solve, we can first set the values of angle E and angle N equal to each other.

WORK:

x^(2) = 4 x^(2) - 75

3 x^(2) = 75

x^(2) = 25

x = 5

Now that we have the value of x, we can plug it in for the angles we need to find.

WORK:
Angle E = 5^2
Angle E = 25
Angle N = 4(5^2) - 75
Angle N = 100 - 75
Angle N = 25

ANSWER:
A - Angle N and Angle E both equal 25

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
