For triangle MNP, find the value of x and the measure of each of the three angles.

Question

at the top of the triangle is X degrees and that is angle M

at the bottom left of the triangle is (2x-1) degrees and that is angle P

at the bottom right of the triangle is (2x+1) degrees and that is angle N

Please help me. I do not understand.

Answer 1

you just have to remember that the angles of a triangle add up to 180 degrees. So, with angles

M+P+N = 180
x + 2x-1 + 2x+1 = 180

Now it's easy to find x, the evaluate the actual angle measures.
