Question

In ΔPQR, ∠P=70º, ∠R=30º. Which side of this triangle is the longest?

Answer 1

Answer:

PR

Step-by-step explanation:

Given, in ΔPQR, ∠P = 70° and ∠R = 30°.

We know that, sum of all the angles of a triangle is 180°.

∠P + ∠Q + ∠R = 180°

We know that here ∠Q is longest, so side PR is longest.

[∴ since in a triangle, the side opposite to the largest angle is the longest]
