Question

In a right triangle, there is a 57° angle. What is the measure of the third angle?

Answer 1

33°

Explanation:

In a right triangle, one angle is always 90 degrees.

Given that one angle is 57 degrees, the sum of the angles in any triangle is always 180 degrees.

Therefore, the third angle in the right triangle can be found by subtracting the sum of the other two angles from 180 degrees:

Third angle = 180° - (90° + 57°)

Third angle = 180° - 147°

Third angle = 33°

Answer 2

The third angle is 33 degrees.

Explanation:

The sum of the angles of a triangle adds to 180 degrees.

We know two of the angles, 57 and a right angle, which is 90 degrees.

57+90 = 147

147+x = 180

x = 180-147

x = 33

The third angle is 33 degrees.
