Application of the Pythagorean Theorem is a quick and easy way to determine the side length of a right-angle triangle. The formula is used extensively for engineering applications. Any side length can be found by transposing the formula. TEST YOUR UNDERSTANDING: From your own work, hobby or interest list how triangle ratios calculations could be applied. For example, a ladder leaning against a wall how long would it need to be to reach roof level or at what point does it become unsafe or maybe think of a sport application? Pythagorean theorem for a right-angle triangle where the adjacent is 48.94cm and the opposite is 33.62cm. Calculate the length of the hypotenuse. Choose answer option: A = 59.38cm | B = 74.22cm | C = 65.31cm | D =89.06cm Angle using sine, the values of hypotenuse = 70.80cm and opposite = 30cm for two sides of a right-angle triangle. Calculate the angle ø. Choose Answer option: A = 25.07° | B = 18.80° | C = 37.61° | D =22.56° Find Adjacent using Cos. Given that the angle ø for a right-angle triangle is 43.48° and the length of the hypotenuse is 91.27cm. Calculate the length of the adjacent side using the Cos scientific function. Choose answer option: A = 33.11cm | B = 72.85cm | C = 82.78cm | D =66.23cm
