Answer:
Step-by-step explanation:
Speed v = distance d/time t
v = 14km/h, t = 2 1/2hr = 5/2hrs
: 14 = d/(5/2)
14 = 2d/5
14 × 5 = 2d
d = (14× 5)/2
d = 35km
-6/3
Move down 6 from the top point.
Then move right 3 to the bottom point.
x²+y² = 5²
3²+y² = 25
y² = 16
y = ±√16 = ±4
Since the terminal side is in quadrant IV, y = -4
sinθ = -4/5
