Rotate the axes to eliminate the xy-term in the equation. Then write the equation in standard form. Rotate the coordinate axes through an angle with 0 ≤ ≤ /2. ( Bonus 1 point:Graph the conic in the rotated axes)

boxplot e is the answer

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.

what i would say the best answer is a. 40.5
