Question

if (mangle a) is less than 90, then (angle a) is an acute angle. the measure of (angle a = 75). what can you logically conclude?
a (angle a) is acute
b (angle a) is right
c (angle a) is obtuse
d. not enough information

Explanation:

Step1: Recall angle - type definitions

An acute angle has a measure less than 90 degrees, a right - angle has a measure of 90 degrees, and an obtuse angle has a measure greater than 90 degrees.

Step2: Compare the measure of ∠A with the definitions

Given that \(m\angle A = 75\) degrees and 75 < 90.

Answer:

A. ∠A is acute
