Question

what is the measure of this angle? the dashes are 15° apart

Explanation:

Step1: Identify angle - starting and ending points

The angle starts from $0^{\circ}$ and ends at the third dash after $0^{\circ}$.

Step2: Calculate angle measure

Since dashes are $15^{\circ}$ apart, and there are 3 dashes from $0^{\circ}$, the measure is $15\times3 = 45^{\circ}$.

Answer:

$45^{\circ}$
