Question 1166488: In a triangle, the sum of the measures of the first and the second angles is twice of the measure of the third angle. If the measure of the second angle is 10° less than the measure of the third angle, then find the measures of the three angles.

first            x
second          t-10
third            t
SUM             180





Using this for x, sum of measures of interior angles:



---------------------------------------------
The measures of the three angles:
first        70
second       50
third        60
--------------------------------------------
