Question

In adjoining figure in ∆ ABC, point D is on side AC. If AC= 15, DC=7 and BP⊥AC, then find A(∆ABD)/A(BDC).​

Answer 1

Answer:

Let ABC and PQR be two right triangles with AB ⊥ BC and PQ ⊥ QR.

Given:

BC = 9, AB = 5, PQ = 6 and QR = 10.

∴

A(△ABC)

A(△PQR)

=

AB×BC

PQ×QR

=

5×9

6×10

=

3
