Answer:
sin(25 degrees)/2 = 0.21
Explanation:
Since the sine of an angle is the opposite side divided by the hypotenuse, the sine of 25 degrees equals the opposite, or 2, divided by the hypotenuse, or what you are trying to find. So sin(25 degrees) = 2/x, or x = sin(25 degrees)/2, and using your calculator and rounding, the final answer is 0.21
