find the measure of the missing angle.\nanswer attempt 1 out of 2\na =

Answer:

$23^{\circ}$

Explanation:

Step1: Recall angle - sum property

The sum of angles in a right - angled corner is $90^{\circ}$.

Step2: Set up the equation

Let the missing angle be $a$. We have $a + 67^{\circ}=90^{\circ}$.

Step3: Solve for $a$

$a=90^{\circ}-67^{\circ}=23^{\circ}$
