In a triangle ABC measure of a =80c the measure of b is fifteen more then nine times the measure of c fun measure of b and c
----
a = 80*c
b = 9c + 15
c = c
---------
Equation:
a + b + c = 180 degrees
80c + 9c+15 + c = 180
90c + 15 = 180
90c = 165
c = 1.8333 degrees
a = 146.667 degrees
b = 31.5 degrees
