You can use trigonometry to solve this one. Which one deals with the opposite side and the hypotenuse?
OpenStudy (anonymous):
yes but can you show me step by step the process
OpenStudy (anonymous):
Okay, so we know that we're dealing with an angle (a), we're given the hypotenuse (y), and we're trying to find the opposite side (x). We know that sin a = opposite / hypotenuse = x / y. Now we just have to plug in the values: sin 61 = x / 17.4 and solve for x using a calculator.
