Question

Which of the following numbers are cubes of even natural numbers ? (a) 64 () 216 (c) 343 (d) bers?​

Answer 1

Answer:

Step-by-step explanation:

In △ABC and △PQR

∠C=∠P (Given)

∠B=∠Q (Given)

∠A=∠R (Third angle of the triangle)

Thus, △ABC∼△PQR

Also, given, AB=AC

Thus, ∠B=∠C (Isosceles triangle Property)

But, ∠B=∠Q and ∠C=∠P

Hence, ∠Q=∠P

or PR=QR

Thus, both the triangles are Isosceles but not congruent.

Answer 2

Answer:

(a) 64 (b) 216 are the correct answer.

Step-by-step explanation:

$64 \\ = {4}^{3}$

$216 \\ = {6}^{3}$
