Question

In the given figure, if angl A= 90 degree ,angle B=90 degree, OB=4.5 cm,OA=6 cm and AP= 4 cm, then find QB

Answer 1

Answer:

Quite is 3cm ok best of luck to you

Answer 2

Answer:

3cm

Explanation:

In ∆AOP and ∆QOB

∠A=∠B=90°,

∠AOP=∠QOB (vertically opposite angle)

OA=OB

∴ΔAOP and ΔQOB are similar Δs

∴OA/OB=AP/QB (in similar Δs the ratio of corresponding sides are constants)

QB= AP× OA/OB

QB=3cm

Hope it helps you
