Step-by-step explanation:

To find the probablility, add all of the possibilities. Then, divide the outcome by the total possibilities.

x+3x+5x+4x=13x

x/13x=1/13.

So, the probabilit is 1/13.

check the picture below.

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,
