Answer:
∠B = 90°
Step-by-step explanation:
Given that in ΔABC,
AC = √7, AB = 2 and BC = √3
We observe that for the given triangle:
AC² = AB² + BC²
⇒ (√7)² = 2² + (√3)²
From Pythagorean Theorem we know that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.
Therefore AC is the hypotenuse and ∠B = 90°
