A landscaper is forming an isosceles triangle in a flowerbed using chrysanthemums. She wants m∠A to be three times the measure of ∠B and ∠C. What should the measure of each angle be?
Step 11 of 2
We let so that .
By Triangle Angle-Sum Theorem, the sum of the measures of the angles of a triangle is 180 so we can write:
Divide both sides by 5:
