Question

solve this que geomatry​

Answer 1

Step-by-step explanation:

SincePA, QB and RC are each perpendicular to AC.

Hence, PA∥QB∥RC

In△APC

y/x = bc/ac (by Basic proportionality theorem..)...(1)

In△ARC

y/z = ab/ac (by BPT..)

Adding(1)and(2)

y/x + y/z = (ab+bc)/ac

taking y common

y[1/x+1/z] = ac/ac = 1

taking y to RHS

WE GET,

1/x+1/z = 1/y
