the second angle is a triangle is one and a half times the measure of the first. the third is 15 degree more than half the first angle. find the measure of each angles in the triangle
------
Let 1st be "x"
Then 2nd is 1.5x
And 3rd (x/2)+15
------------------------
Equation:
x + 1.5x + (x/2) + 15 = 180
----
2x + 3x + x = 360-30
6x = 330
x = 55
1st = x = 55 degrees
2nd = 82.5 degrees
3rd = 42.5 degrees
