Tanya has a triangular garden bed in her back yard. The measure of the largest angle is 30° less than twice the measure of the smallest, and the measure of the middle angle is 10° more than the measure of the smallest angle. Find the measures of the three angles. Start your work by defining the unknown quantities in terms of a variable. Show all work and write a complete answer, including units.
(If someone could break down the method to finding this it would really help)
