Question

one angle of a triangle is 3 times as large as another the third angle is twice the sum of the first two angles what is the measure of the largest angle?

Answer 1

180 Degrees = 3x + x + 2(3x + x)
180 = 4x + 8x
180 = 12x
x = 15

Substitute for largest angle.
2(3(15) + 15)
120 Degrees is the largest angles degree.

Answer 2
