Each part of the ratio represents the fractional part of the total angle measurement of the triangle (180 degrees). Ex. Angle A is 8/15 of the sum of the angles, angle b is 3/15, etc. therefore, your answer would be 36 degrees.

step-by-step explanation:
there is a formula i can give you:
it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.
