what is the value of x?

➷ We can use the sine rule to determine this

First calculate the length CB

CB = (6 / sin(90)) x sin(45)

CB = 6

180 - (60 + 90) = 30

Angle BCD equals 30 degrees

Now use the sine rule again to calculate x

x = (6/sin(90) x sin(30)

x = 3

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

instagram is better than go there instead lol

step-by-step explanation:

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,
