represent the measure of the smallest angle. Then the measure of the largest angle must be

and the measure of the third angle must be

. Since the sum of the measures of the three angles of any triangle is 180°, we can write:\r

to get the measure of the smallest angle. Multiply that by 3 to get the measure of the largest, and add 20 to it to get the measure of the third one.\r
