Question

How to do number 12 please and explain ?

Answer 1

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!! :)
