Question

Draw a parallelogram PQRS in which PQ = 4 cm, ∠ P =1050

, ∠ Q = 1250

,

∠ S = 500

and SP = 5.6 cm.


Q 29) Find the smallest number by which 79380 could be multiplied or divided to get a perfect

square.

Q 30) Which is the smallest number that must be multiplied by 385875 to make it a perfect cube?​

Answer 1

Answer:

⇒ Draw a line segment QR = 4.5cm.

⇒ Construct an angles of 110

∘

and 80

∘

at points Q and R.

⇒ Cut off PQ = 3.5cm and RS = 4cm.

⇒ Join PS.

⇒ Measure angle at point P.

⇒ We get ∠P=78

∘

.
