The angle measures in triangle ABC are (d) m∠A = 60°, m∠B = 30°, m∠C = 90°
The side lengths are given as:
AB = 12 inches
BC = 6√3 inches
CA = 6 inches
From the list of options, the angles are 30°, 60° and 90°, respectively.
In a triangle, the angle opposite the largest side is the largest angle and vice versa.
This means that:
∠C = 90° --- opposite AB
∠A = 60° --- opposite BC
∠B = 30° --- opposite CA
Hence, the angle measures in triangle ABC are (d) m∠A = 60°, m∠B = 30°, m∠C = 90°
