Point a is on a number line halfway between −17−17 and 55. point b is halfway between point a and 0. what integer does the point b represent?

do you have the measurements?

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,
