Question

PQR is a triangle, right angled at P. If PQ=8cm and PR=36cm.Find QR.​

Answer 1

Answer:

The Value Of QR = 4√85 cm.

Step-by-step explanation:

From the adjoining figure, (given in the attachment):

In ΔPQR:-

Hypotenuse = QR

Perpendicular = PQ

Base = PR

According to Pythagoras theorem,

PQ² + PR² = QR²

=> QR² = PQ² + PR²

=> QR² = 8² + 36²

=> QR² = 64 +  1296

=> QR² = 1360

=> QR = √1360

=> QR = 4√85

:. QR = 4√85 cm

You need not take heed of the answer coming weird as 4√85 cm as it is probable to come so.

Answer 2

Note: Refer to the adjoining attachment.

★$\bf{\underline{Answer::}}$

➢ In ΔPQR:

➥ QR² = PQ² + PR²

➥ 8² + 36²

➥ QR² = 64 + 1296

➥ QR =  $\sqrt{1360}$

Therefore,

➠ QR = 36.88 cm [Approx.]

★$\bf{\underline{Steps::}}$

• We used Pythagoras Theorem to find our answer.
• It says that Square of Hypotenuse is equal to Square of both the other sides added up.
• In this way, we calculated QR which is equal to 36.88 cm.
