Question 4 [16] In the following excercise the right angled ?XYZ is given: 4.1 In the given triangle there are three sides. Write down which one of the sides XY, YZ or XZ will be the: • opposite side of 35,3": YZ • adjacent side of 35,3": XY • hypotenuse of the rightangled triangle: XZ [3] 4.2 If YZ is the WANTED SIDE and XZ is the GIVEN SIDE, which ratio of o/h = sin 35,3" or a/h = cos 35,3" or o/a = tan 35,3" will you use to determine YZ? [3] o/h = sin 35,3" = 4.3 Use 4.2 to determine YZ, if XZ = 32 cm [5] sin(35,3") = YZ/32 YZ = 32 x sin(35,3") = 18,49 cm

Step 1
The hypotenuse is always the side opposite the right angle and is the longest side. The opposite side is the side opposite the angle in question, and the adjacent side is the side that is next to the angle in question and is not the hypotenuse. Show more…

Consider a right triangle with a side of length x opposite angle A, a side of length y opposite angle B, and a hypotenuse of length z opposite the right angle. If sin B = 1/sqrt(3) and x = 2, find the length of the other side (y) and the length of the hypotenuse (z). Enter the exact answers.
