Question

what is the value of s?

Explanation:

Step1: Recall angle - subtraction principle

The large angle is composed of two non - overlapping angles. To find the smaller angle $s$, we subtract the known smaller angle from the large angle.
Let the large angle be $74^{\circ}$ and the known non - overlapping angle be $47^{\circ}$. Then $s=74^{\circ}- 47^{\circ}$.

Step2: Perform subtraction

$s = 27^{\circ}$

Answer:

$27$
