Brainlist the answer

Step-by-step explanation:

Answer 2

In triangle PAC, we have

BQ||AP therefore, BQ UPON AP = CB SO,, y upon x = CB UPON CA EQ. 1

in triangle ACR, we have

BQ||CR therefore, BQ UPON CR = AB UPON AC SO,, y upon z = AB UPON AC EQ. 2

adding eq. 1 and 2 we get

y upon x + y upon z = CB UPON AC + AB UPON AC

therefore,,,, y upon x + y upon z =( AB + BC ) UPON AC

SO,, y upon x + y upon z = 1

-------- so,,, 1 upon x + 1 upon z = 1 upon y.......

answer is lengthy but easy to understand and some steps are not written but you will understand that......
