Question

in a triangle the 2nd angle measure twice the first and the third angle measures 4 more than the first if the sum of all angles measures is 180 find the measure of all three angles PLEASE NEED SLEEP

Answer 1

Third angle = 120 degrees

All the angles add up to 180 degrees.

Call the smallest angle x, so the second will be 2x and as the third is three times the second it will be 6x. We have:

x+2x+6x=180

9x=180⇒x=20

The third angle is 6x=120
