A playground slide is 14.5 feet long with an 8.5-foot tall ladder. What is the measure of the angle that the slide makes with th
e ground, x, to the nearest degree?
2 answers:
The slide and the ladder made a right angle triangle with the ground. The angle that the slide made with the ground is labeled as 
in the diagram below. We can use the trigonometry ratio to work out the size of the angle.
8.3 is the side opposite to the angle and 14.5 is the hypotenuse. We need to use the Sin ratio

Answer:
type 2 in the first box,
13/4 in the second box, and
-9/8 in the third one
Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:
Which in our case is: -13/4
and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:
Then your expression for this quadratic should be:
Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one
