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.

Find the ratio of x to y. X/5=2/3=5/y 2/3 4/9 1

just olya [345]

Answer:

x= 4/9

Step-by-step explanation:

$\frac{x}{5} = \frac{2}{3}$

$x = \frac{10}{3}$

Again,

$\frac{2}{3} = \frac{5}{y}$

$y = \frac{15}{2}$

$\frac{x}{y} = \frac{ \frac{10}{3} }{ \frac{15}{3} }$

$\frac{x}{y} = \frac{4}{9}$
