Question

value: 1
find the measure of the arc.
110°
?
a. 110°
b. 55°
c. 70°
d. 250°

Explanation:

Step1: Recall circle - arc relationship

The sum of the measures of the arcs of a circle is 360°.

Step2: Calculate the unknown arc measure

Let the unknown arc measure be $x$. We know one arc is 110°. So, $x+110^{\circ}=360^{\circ}$. Solving for $x$, we get $x = 360^{\circ}-110^{\circ}=250^{\circ}$.

Answer:

d. 250°
