Can anyone me with this problem? ?

9.

Step-by-step explanation:

So basically, we need to find out x. So we know that ZX = YW because ZY and XY are already congruent and it's just adding a three to the value because of YX. We can find out x.

ZX = YW

5x + 17 = 10 - 2x

x = -1

Then we can find out the value of ZX and YW by plugging in x.

5(-1) + 17 = ZX = YW = 12.

Then we see that YX is 3 so...

ZX = ZY + YX

12 = ZY + 3

ZY = 9

So the answer is 9.

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,

the answer for your question is
