Question

In a​ triangle, the measure of the first angle is three times the measure of the second angle. The measure of the third angle is 80 degrees more than the measure of the second angle. Use the fact that the sum of the measures of the three angles of a triangle is 180degrees to find the measure of each angle.

Answer 1

1st Angle - 60

2nd Angle - 20

3rd Angle - 100

Explanation:

Not sure if it really needs an explanation. 60 is 3 times as much as 20, and 100 is 80 more than 20. All together, it makes 180 degrees.
