Janelle flies her kite several feet in the air. She then reels the kite in at a constant number of feet per minute. The equation y=-18+ 240 represents this situation, where x is the number of minutes and y is the height of the kite in the air. What does the number -18 in the equation represent? A. The kite is 18 feet above the ground before Janelle starts reeling it in.

B. The kite ascends 18 feet per minute.

C. The kite descends 18 feet per minute.

D. The kite is 18 feet above the ground after Janelle is done reeling it in.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
