Question

in ∆pqr if xy||pq px=5 xr=3 and qr =7.2 then find the value of ry​

Answer 1

Answer:15

Step-by-step explanation:

Answer 2

Therefore the length of RY is 2.7 units.

Given:

In ∆QPR, XY is parallel to PQ

The length of the line segment PX = 5 units

The length of the line segment XR = 3 units

The length of the line segment QR = 7.2

To Find:

The length of the line segment RY.

Solution:

The given question can be solved as shown below.

The length of the side PR = PX + QR = 5 + 3 = 8 units

In ∆QPR and ∆XYP, XY ║ PQ, and R is the same vertex for both the triangles, so both triangles are proportional to each other.

So the ratio of the sides must be proportional.

⇒ PR/XR = QR/YR

⇒ 8/3 = 7.2/RY

⇒ RY = ( 7.2 × 3 ) / 8

⇒ RY = 2.7

Therefore the length of RY is 2.7 units.
