Question

386. One angle of a triangle is twice the measure of the smallest angle. The third angle is 60° more than the measure of the smallest angle. Find the measures of all three angles.

Answer 1

Explanation:

s = smallest angel

2s = twice the smallest

60 + s = third angle

summed they = 180 degrees

s + 2s + (60+s) = 180

4s + 60 = 180

4s = 120

s = 30 then 2s = 60 and the third angle = 60 + 30 = 90 degrees
