In a right-angled triangle ABC, angle A = 60 degrees, leg CB, which lies opposite to it = 2√3. Find the hypotenuse AB.
According to trigonometric ratios in a right-angled triangle, we will use the formula: sin 60 = CB / AB.
(sin 60 = √3 / 2)
√3 / 2 = 2√3 / AB;
AB = 2 * 2√3 / √3;
AB = 4 (cm).
Answer: 4 cm.
