Question

what is the measure of this angle? choose the best estimate.$45^circ$$110^circ$$10^circ$$65^circ$

Explanation:

Step1: Compare angle to benchmarks

A right angle is $90^\circ$, this angle is much smaller. $45^\circ$ is half a right angle, and this angle is far narrower than that.

Step2: Match to smallest option

The only option that fits a very narrow angle between two close rays is $10^\circ$.

Answer:

C. $10^\circ$
