Constants s who successfully complote this primer will be Part A-Finding an unknown side when you know the two other sides Determine the length of a side of a right briangle, iven the length of the two other sides Determine the length of a side of a right triangle, jiven the length of one other side and an angle Your GPS shows that your friend's there directhy. You know your friend house? house its 10 0 kin away (Figure 2). But there is a big hill between your houses and you don't want to bike s street is 6 0 km novth of youar street How far do you have to ride before turing north to get to your liends View Available Hint(s) working on this primer, you may need to review The meaning and application of the mnemonic ? itional practice, you may want to review Right Triangle tions krnExplanation / Answer
(A) R^2 = x^2 + y^2
10^2 = x^2 + 6^2
x = 8 km
(B) cos(theta) = 6 / 10 = 0.6
theta = cos^-1(0.6)
= 53 deg
