Solution

The correct option is A AB
Given,
$∠ A = 70^{\circ}$
$∠ B = 30^{\circ}$
Therefore,
$∠ C = 180 - (70 + 30) = 180 - 100 = 80^{\circ}$
Longest side will be opposite to the largest angle.
Hence, AB is the longest side.

In triangle ABC, ∠A=70∘and∠B=30∘. Which side of the triangle ABC is the longest?

The correct option is A ABGiven, ∠A=70∘ ∠B=30∘ Therefore, ∠C=180−(70+30)=180−100=80∘ Longest side will be opposite to the largest angle. Hence, AB is the longest side.

In triangle ABC, $∠ A = 70^{\circ} a n d ∠ B = 30^{\circ}$ . Which side of the triangle ABC is the longest?

The correct option is A AB
Given,
$∠ A = 70^{\circ}$
$∠ B = 30^{\circ}$
Therefore,
$∠ C = 180 - (70 + 30) = 180 - 100 = 80^{\circ}$
Longest side will be opposite to the largest angle.
Hence, AB is the longest side.
