B, 7/24

Step-by-step explanation:

(x=theta)

sec(x) = 1/cos(x) so 1/cos(x) = 25/24

Then use the cos^-1 function on your calculator to find out theta.

Then tan your found value of theta.

You should find that tan (theta) = 7/24

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,
