5) Surveyors wished to know the distance across a lake between A and B. They measured the distance from B
to C as 100 m and the angle from C to A to be 56º.
Knowing that the angle between CB and BA was 90°,
they used trig to solve for the distance. Show how it
was done

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

7 is the median   7.875 is the mean
