Point M and N lie 250 m apart on opposite sides of a hill. The angle of elevation to the top of the hill from Mand N are 55° and 48°, respectively. Calculate the height of the
hill.

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
