Question

In a right triangle, the acute angles measure x + 15 and 2x degrees. What is the measure of the smallest angle of the triangle?

Answer 1

So in a triangle we know that all angles add up to 180, yes?

Answer 2

and in a right triangle on of the angles is 45

Answer 3

so if we add up all the angles, they should sum to 180
45+(x+15)+2x=180

Answer 4

you can solve for x and then plug the x-value back into x+15 and 2x to see which is smaller
