The measure of one acute angle in this right triangle is 23°. What is the measure of the other acute angle?

A. 42°

B. 67°

C. 132°

D. 157°

B. 67°

Step-by-step explanation:

An acute angle is an angle that has a degree that's less than 90°. This eliminates answers "C," and "D."

The information above states that the triangle is right, meaning that one of its angles is 90°, and there's another angle that's 23°.

So add these together, and subtract from 180 (all triangles are 180°), to get the other acute angle:

90 + 23 = 113

180 - 113 = 67°

The missing acute angle is 67°
