The following coordinates are known with respect to a Cartesian system with origins in O, referring to the four points A, B, C and D: Xa = -50.58 m; Ya = 17.81 m XB = -35.07 m; YB = -28.56 m Xc = 38.87 m; Yc = -33.75 m Xd= 29.66 m; Yd= 63.42 m Calculates: • the internal angles, in hundredth degrees, of the quadrilateral ABCD; • the perimeter and area of the ABCD quadrilateral; • the coordinates of the point K intersection of the two diagonals of the quadrilateral.

answer: y=4000x+14000

step-by-step explanation:

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.
