In ΔABC, sides are given as AB = 6√3 cm, AC = 12 cm, and BC = 6 cm.
We’ll find the measure of ∠A step by step!
Since AB² + BC² = AC², the triangle is right-angled at B.
Using the 30°–60°–90° relationship —
Half of the hypotenuse = side opposite 30°,
and side √3/2 × hypotenuse = side opposite 60°.
Hence, ∠A = 30°.
