Graph x is greater than or equal to 4

i assume that by 5 you mean 5 gallons.

(20)(0.25) = 15

removing 15 gallons reduces the tank from 20 to 5.

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,

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

i think the correct option is the second option.
