Question

find the unknown angle measure

Explanation:

Step1: Identify the right angle

The vertical and horizontal lines form a right angle, so the total angle is \( 90^\circ \).

Step2: Calculate the unknown angle

We know one angle is \( 63^\circ \), so to find \( x \), we subtract \( 63^\circ \) from \( 90^\circ \).

$$ x = 90^\circ - 63^\circ = 27^\circ $$

Answer:

\( 27^\circ \)
