Question 1171141: In triangle ABC, measure a = 4x , measure b = 6x +7 and measure c = 7x -11. How would I find all three angles for this measurement, I don’t understand.

The three angles add to 180 degrees, since this is a triangle
so 4x+6x+7+7x-11=180
17x-4=180
17x=184
x=10.823 deg
so a is 43.29 degrees (4*10.823)
b is 71.94 degrees
c is 64.76 degrees add to 179.99 (rounding).
