Question

1. find the missing measure. 4. if the measure of an angle is

Explanation:

Step1: Recall angle - sum property

The sum of the two non - right angles in a right - angled triangle (or in this case, the two angles that make up the right angle) is 90°.

Step2: Set up the equation

Let the unknown angle be $x$. We know that $x + 65^{\circ}=90^{\circ}$.

Step3: Solve for $x$

$x=90^{\circ}- 65^{\circ}$.
$x = 25^{\circ}$

Answer:

$25^{\circ}$
