▼

- Identify the sides: The side labeled 'x' is opposite the 53° angle, and the side labeled '15' is the hypotenuse.
- Choose the correct trigonometric ratio: Since we have the opposite side and the hypotenuse, use the sine function: sin(θ) = opposite / hypotenuse.
- Set up the equation: sin(53°) = x / 15.
- Solve for x: Multiply both sides by 15 to isolate x: x = 15 * sin(53°).
- Calculate the value: Using a calculator, sin(53°) ≈ 0.7986. Therefore, x ≈ 15 * 0.7986 ≈ 11.98.
- Round the answer: Rounding to two decimal places, x ≈ 11.98.
