Scott needs to buy fencing for his yard. He finds a table at the store that shows him the price of fencing (C) based on the number of feet purchased (x). Which function could model the cost of fencing? A) C=1/4x B) C=4x C) C=x^2 D) C=4*2^x

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,

they are simplified
