Question 348142: hey how are you? i really need help on this qs...
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?
the choices are
A.) A and B:25; C:130
B)A and B:15 ; C:150
C). A and C:130, B:25
D)A and B: 150, C:15
i think the answer is A but imnot suree??

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
