A right triangle has one angle measuring 30° and the hypotenuse is 20 cm. What is the length of the side opposite the 30° angle?
Q1. A right triangle has one angle measuring 30° and the hypotenuse is 20 cm. What is the length of the side opposite the 30° angle?
Answer: 10 cm
Explanation: The sine of 30° equals the ratio of the opposite side to the hypotenuse. Since sin(30°) = 0.5, the length is 20 * 0.5 = 10 cm, applying the formula sin(angle) = opposite/hypotenuse.
