Answer:

NOT proportional.

Step-by-step explanation:

Get a common denominator of 21 by multiplying 7 and 3 by 3.

$\frac{3}{7}(\frac{3}{3})=\frac{9}{21}$

When both fractions have the same denominator, their numerators are different. Therefore, they are NOT proportional.

Construct parallelogram PQRS<br>with |PQ|=10cm, |ps|=8cm and<br><QPS = 120

IgorC [24]

Find sketch of parallelogram attached

Answer and explanation:

A parallelogram is a quadrilateral which is wider than it is long. A parallelogram has two sides parallel to the other. From the above, we are told the parallelogram PQRS has an angle QPS 120, with sides 10cm and 8cm, we use this to sketch the parallelogram

We find that angle QPS is 120 degrees hence angle RSP is 60 degrees since angle on straight line is 60 degrees from 180-120 in angle QPS and alternate angles are equal. Also opposite angles of a parallelogram are equal
