Answer:
E and N both equal 25
Step-by-step explanation:
The squares at the bottom of the triangles mean that angle D and angle M are 90˚ angles. We also know that angle F and angle P are equal to eachother. This proves that the triangles have equal angle measures, and that the measure of N and E are the same.
x^2 = 4x^2 - 75
Subtract 4x^2 from both sides.
x^2 - 4x^2 = 4x^2 - 75 - 4x^2
Divide both sides by -3
-3x^2/-3 = -75/-3
x^2 = 25
