Question

What is the length of the opposite leg with a hypotenuse measuring 120cm and an angle of 5 degrees

Answer 1

Explanation:

The function you want to use is the sign function.

Formula

Sin(theta) = Opposite / hypotenuse

Givens

• Theta = 5 degrees
• Hypotenuse = 120 cm
• Opposite = ??

Solution

sin(5) = opposite / 120 Multiply both sides by 120

120 * sin(5) = opposite.

Sin(5) = 0.0872

120 * 0.0872 = opposite

10.4587 = opposite
