A circle has a radius of 5ft, and an arc of length 7ft is made by the intersection of the circle with a central angle. Which equation gives the measure of the central angle, q?

A. Theta=5/7
B. Theta=7/5
C. Theta=7+5
D. Theta=7•5

Respuesta :

Answer: Theta = 7/5

Step-by-step explanation:

Use the arc length formula [tex]s=r(theta)[/tex]

Rearrange the formula since you are wanting to solve for theta

so [tex]theta = \frac{s}{r}[/tex]

Plug in

theta = 7/5
