Question 498059: In a triangle, the measure of the first angle is 3 times the measure of the 2nd angle. The measure of the third angle is 45 degrees more than the measure of the second angle. use the fact that the sum of the measures of the three angles of a triangle is 180 degrees to find the measure of each angle.

A = 3x
B = x
C = x + 45
==================================
3x + x + x + 45 = 180.
5x + 45 = 180
5x = 135
x = 27
=================================
A = 3(27) = 81 degrees
B = 27 degrees
C = 27 + 45 = 72 degrees.
72 + 27 + 81 = 180 degrees.
This does check.
