You can put this solution on YOUR website! Angle A = 3x, B = 5y, C = 9x
A and B are complementary angles and C and B are suplementary angles.
---------------
Equations:
3x + 5y = 90
9x + 5y = 180
-----
Subtract and solve for "x":
6x = 90
x = 15 degrees
------
Solve for "y":
3x + 5y = 90
45 + 5y = 90
5y = 45
y = 9 degrees
----
A = 3x = 45 degrees
B = 5y = 45 degrees
C = 9x = 135 degrees
