A circle has a radius of 5 ft, and an arc of length 7 ft is made by the intersection of the circle with a central angle. Which equation gives the measure of the central angle, q?
Theta= five-sevenths
Theta = Seven-fifths
Theta = 7 + 5
Theta = 7 times 5

Theta = 7/5

Step-by-step explanation:

Use the arc length formula s=r(theta)

Rearrange the formula since you are wanting to solve for theta

so theta = \frac{s}{r}

Plug in

theta = 7/5

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
