Question

In a right-angled triangle PQR the hypotenuse is the side PR.

The length of side PQ is 20cm and the ratio RQ:PQ is 1:2

What is the length of the perpendicular from the hypotenuse to the point Q?

Answer 1

The answer is 10cm

Explanation:

the ratio RQ:PQ=1:2

let the ratios be multiplied by x

1x:2x

but 2x=20

then x=10.

so the length is 10cm
