Question

the measure of one angle of a triangle is 66°. of the remaining two angles, one is twice the measure of the other. how could you find the measures of the two unknown angles?

Answer 1

below

Explanation:

x = one angle and the other = 2x

solve this to find 'x' and '2x'

x + 2x + 66 = 180 because all of the angles of a triangle = 180
