Need help asap with these would be greatly appreciated

1.) 5,0,-3, -6,-3,0,5 (use the points for the graph and connect them together)

2.a) (0,9) He is starting at the heighest point of the ramp, its the height of where he starts walking.

b.) (10,4) The point where they both are at the same height, at the same time.

c.) (18,0) This is when he reaches to ground level or to 0 feet after a certain amount of time, 18 seconds.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
