Here are the essential concepts you must grasp in order to answer the question correctly.
Right Triangle Properties
A right triangle has one angle measuring 90 degrees, and the other two angles are complementary, summing to 90 degrees. The sides of a right triangle are categorized as the hypotenuse (the side opposite the right angle) and the two legs (the other two sides). Understanding these properties is essential for applying trigonometric functions to find unknown side lengths or angles.

Trigonometric Ratios
Trigonometric ratios relate the angles of a triangle to the lengths of its sides. The primary ratios are sine (sin), cosine (cos), and tangent (tan). For a given angle in a right triangle, sin is the ratio of the opposite side to the hypotenuse, cos is the ratio of the adjacent side to the hypotenuse, and tan is the ratio of the opposite side to the adjacent side. These ratios are crucial for solving for unknown sides or angles.

Rounding and Measurement
In practical applications, measurements often need to be rounded to a specified degree of accuracy. In this context, rounding to the nearest whole number means adjusting the calculated side length to the closest integer. This is important for ensuring that the final answer is practical and usable in real-world scenarios, especially in fields like construction or engineering.
