Question

Please help. Last chance to get my diploma

In a right triangle, the acute angles measure x + 15 and 2x degrees.

What is the measure of the larger acute angle of the triangle?



15°

25°

40°

50°

Answer 1

I think its 50 but don't count on me.

Answer 2

How did you get it?

Answer 3

I think i got it wrong. hold on.

Answer 4

Nevermind, its 50. The angles in a triangle sum to 180 degrees. So as the right angle is 90, the other two must total 180 - 90 = 90.

So, x+15 + 2x = 90
Therefore 3x = 90 - 15 = 75
and so x=25.

So the smaller angles are x+15 = 40 degrees and 2x=50 degrees.
So the larger one is 50 degrees.
