You can put this solution on YOUR website! Find the measure of the interior angles. This is a triangle. Show all work.
measure of angle a = X+30
measure of angle b = 4x
measure of angle c = x+60.
Find the measure of A, B, and C
=======================================
a + b + c = 180 degrees
---
x+30 + 4x + x+60 = 180
6x + 90 = 180
6x = 90
x = 15
---
angle a = x+30 = 15+30 = 45 degrees
angle b = 4x = 4*15 = 60 degrees
angle c = x+60 = 15+60 = 75 degrees
==========================================
