Triangle NQP is an equilateral triangle with the measure of angle N=5x-2y and the measure of angle P=x+2y. Find the values of x and y.

Answer 1

Clue: isn't each angle of an equilateral angle equal to 60º ?

Answer 2

if NQP is an equilateral triangle measure of the angle N and P must be equal to 60.
5x-2y=60
x+2y=60
------------
6x=120
x=20 and also y=20
