Through: (-3, 3), slope = 0
how do i do this?

Step-by-step explanation:

If a slope is equal 0, then a line is a horizontal line.

The equation of a horizontal line is:

y = a, where a is any real number.

A line passes through the point (-3, 3) → x = -3 and y = 3.

Therefore the equation is y = 3

answer: do you still need this?

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,
