Answer 1

(a)

Explanation:

Given 3 sides of a triangle a, b and c where c is the longest side, then

• If a² + b² = c² ⇒ triangle is right

• If a² + b² > c² ⇒ triangle is acute

• If a² + b² < c² ⇒ triangle is obtuse

Here a = 65, b = 72 and c = 96

65² + 72² ? 96²

4225 + 5184 ? 9216

9409 > 9216 ⇒ triangle is acute

Answer 2

Explanation:

65 - Acute

72 - Acute

96 - Obtuse
