We will be using the cosine function to figure this out.
The ramp, ground, and platform form a right triangle.
The hypotenuse is 29, and the side adjacent to ∠x is 20.
SO:
Cos ∠x = 20/29
Cos ∠x = 0.68965517241379
Use the function on your calculator to find what angle has a Cos of 0.6896551
Cos 0.6896551 = 46.397°
ANSWER: the angle of elevation is 46.4°
Hope this helps! God bless. :)
Answer:
D. 14 units
Step-by-step explanation:
it is a rectangle.
that means both diagonals are equally long.
E is in the middle of of diagonals.
so, since the whole diagonal (AC = DB) is 28 units long, one half of such a diagonal (AE = EC = DE = EB) is then
28/2 = 14 units long.
30%25=7.5
25-7.5=17.5
So the original price of Harry's three T-shirts will be $17.50
