Question

please solve the marked number

Answer 1

Answer:

Step-by-step explanation:

let ab=dc=5x

;.pa=3x ,pb=2x

dq=x and cq=4x

now in trngle arp and crq

∠arp=∠crq   [v.o.a]

∠apr=∠cqr    [alternate ∠'s]

so these two Δ's r similar by [aa criteria]

∴ ap/cq = ar/rc     c.p.c.t

3x/4x = ar/rc

ar/rc = 3/4

let ar=3y and rc =4y

∴ac = 3y +4y =7y

now ar/rc = 3y/7y =3/7

ar=3/7 of rc
