In a right triangle, if one angle measures 30 degrees, what is the measure of the other non-right angle?

In a right triangle, if one angle measures 30 degrees, what is the measure of the other non-right angle?

• A. 30 degrees
• B. 45 degrees
• C. 60 degrees
• D. 90 degrees

Answer: (C)

In a right triangle, the angles add up to 180 degrees. Since one angle is 90 degrees (the right angle), the sum of the other two angles must be 90 degrees as well. If one of the non-right angles is given as 30 degrees, we can find the measure of the other angle by subtracting 30 degrees from 90 degrees. This results in: 90 degrees - 30 degrees = 60 degrees. Thus, the measure of the other non-right angle in the triangle is 60 degrees, which is the correct answer.

If one of the non-right angles is given as 30 degrees, we can find the measure of the other angle by subtracting 30 degrees from 90 degrees. This results in:

90 degrees - 30 degrees = 60 degrees.

Thus, the measure of the other non-right angle in the triangle is 60 degrees, which is the correct answer.
