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

Answer:
M = 36
N = 73
P = 71
Step-by-step explanation:
Add the three measures together and set them equal to 180° since there are 180° in a triangle.
x + 2x + 1 + 2x - 1 = 180
5x = 180
5x/5 = 180/5
x = 36
Find N
2x + 1
2(36) + 1
72 + 1 = 73
Find P
2x - 1
2(36) - 1
72 - 1 = 71
Answer:
x=36
angle P=71
angle N=73
angle M=36
