Question

one angle of a right triangle measures 5°. what is the measure of the other acute angle?

Explanation:

Step1: Sum of triangle angles

The total sum of angles in a triangle is $180^\circ$. A right triangle has one $90^\circ$ angle.

Step2: Subtract known angles

Subtract the right angle and the given $5^\circ$ angle from $180^\circ$.
$180^\circ - 90^\circ - 5^\circ$

Step3: Calculate the result

Simplify the expression to find the unknown angle.
$90^\circ - 5^\circ = 85^\circ$

Answer:

$85^\circ$
