In a right triangle, if one of the angles measures 45 degrees, what is the measure of the other non-right angle?

• 45 degrees

• 90 degrees

• 135 degrees

• 180 degrees

Answer explanation

In a right triangle, the sum of the two non-right angles is 90 degrees. If one angle is 45 degrees, the other non-right angle must be 45 degrees as well to add up to 90 degrees.

If one angle in a triangle is 90 degrees and the second angle is 30 degrees, what is the measure of the third angle?

• 30 degrees

• 60 degrees

• 90 degrees

• 120 degrees

Answer explanation

The sum of angles in a triangle is always 180 degrees. Therefore, the third angle would be 180 - 90 - 30 = 60 degrees.
