Question

In a triangle, the measure of the first angle is three timesthree times the measure of the second angle. The measure of the third angle is 55 degrees55° 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

s + 3s + s + 55 = 180

5s = 125

s = 25

 

3(25) = 75

 

25 + 55 = 80
