Aplanet follows an elliptical path described by x squared plus y squared equals 1.x2+y2=1. a comet follows the parabolic path y equals x squared minus 1.y=x2−1. where might the comet intersect the orbiting planet?

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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.

you already gave the answer
