HURRY!!!!! I NEED HELP!!!!! Find Arc MN A. 20 b.60 c.66 d.120

Ad libitum [116K]

We have been given a circle. We are asked to find the measure of arc MN.

We know that the measure of all arcs in a circle is equal to 360 degrees. SO we can set an equation as:

$\widehat{MN}+\widehat{NO}+\widehat{OL}+\widehat{LM}=360^{\circ}$

Upon substituting our given values, we will get:

$\widehat{MN}+110^{\circ}+130^{\circ}+54^{\circ}=360^{\circ}$

$\widehat{MN}+294^{\circ}=360^{\circ}$

$\widehat{MN}+294^{\circ}-294^{\circ}=360^{\circ}-294^{\circ}$

$\widehat{MN}=66^{\circ}$

Therefore, measure of arc MN is 66 degrees and option 'c' is the correct choice.
