Answer: 6.25 miles
Step-by-step explanation:
Convert the 15 minutes to 1/4 hr or .25
now multiply 25*.25=6.25 miles
144 inches. 12 feet in one hour
12 inches per feet
12feet x 12 inches per foot= 144 inches
So this first wants you to find where sin is √3/2 when θ is between π and 3π/2. θ would therefore be located at 2π/3.
Now plug in the value of θ for cosine:
cos (2π/3) = -1/2
And tangent:
tan (2π/3) = -√3/3
