Question

a right triangle has one angle that measures 30°. what is the measure of the other acute angle? ° submit

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is $180^\circ$.

Step2: Identify right triangle angle

A right triangle has one $90^\circ$ angle.

Step3: Calculate the unknown angle

Subtract known angles from $180^\circ$.
$180^\circ - 90^\circ - 30^\circ = 60^\circ$

Answer:

$60$
