Both circle a and circle b have a central angle measuring 135°. the ratio of the radius of circle a to the radius of circle b is 4 7 . if the length of the intercepted arc for circle a is 1 2 π, what is the length of the intercepted arc for circle b? a) 1 2 π b) 2 3 π c) 5 7 π d) 7 8 π

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
