Question 348142
The sum of the measures of the angle of any triangle is 180.In traingle ABC, angles A and B have the same measure, while the measure of angle C is 135 larger than each of A and B. what are the measures of the three angles? 
-----
Equations:
a  + b + c = 180
a  = b
c = a + 135
-----------------------
Substitute for b and c and solve for "a":
a +  a + a+135 = 180
---
3a = 45
a = 15 degrees
b = 15 degrees
c = 150 degrees
