1.	9) In a right angle triangle, one of the other two angles istwice the other. Find the measure of the other angle whichis not a right angle.
Answer» we know that the three angles together equal 180 degrees, so if one is 90 (being a right triangle), then the other two must add up to 90. If x = the measure of the smaller, then the larger is 2x, right? x + 2x = 90 3x = 90 x = 30 The smaller is 30 and the larger is 60.

Answer»

we know that the three angles together equal 180 degrees, so if one is 90 (being a right triangle), then the other two must add up to 90.

If x = the measure of the smaller, then the larger is 2x, right?

x + 2x = 90

3x = 90

x = 30

The smaller is 30 and the larger is 60.
