Which equation has w=8 as the solution? a) Sw=64
b) 16w = 240
c) 16 - W=9
I d) 4+ w= 10

I used process of elimination to solve this: its is A.

I was confused about the 's' in Sw=64 so i decided it had to be either 5 or 8. its 8

8*8=64

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,
