Question

Which of the following is the measure of an acute angle? a. 112, b. 183, c. 90, d. 78

Answer 1

d. 78

Explanation:

An acute angle is an angle with a measure less than 90 degrees,

Hence since 78 < 90, it is an acute angle

Answer 2

d. 78

Explanation:

An acute angle is any angle that measures less than 90 degrees.

From the list of options, we can see that 78 is that angle.

90 is a right angle; 112 is obtuse since it measures more than 90.

This means that d. 78 is the acute angle.
