Question

4.
The figure shows a parallelogram PQRS where
QR = 10 m. If ST = 8 m and SU = 11.2 m, find the
length of PQ.

Answer 1

Answer:

SR=14

Step-by-step explanation:

As QR= 10; SP = 10

So wiith trig ratios, use sin with the opposite side (8) and hypotenuse (10) to get that angle SPQ is about 53 degrees. And this is the same angle for SRQ as well.

Use the sin 53 with the opposite side in triangle SUR (11.2) to give you the length of side SR.

As PQRS being a parallelogram hence, the sides PQ and SR are equal.
