1. What value will be in cell C1 after the formula is entered?

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

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.

yes ok                                            

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
