A hill slopes at an angle of 12.5° with the horizontal. From the base of the hill, the angle of inclination of a 459 foot tower at the top of the hill is 36. How much rope would be required to reach from the top of the tower to the bottom
of the hill (round to the nearest integer)?
c)
A)
188 feet
B)
424 feet
665 feet
D)
1124 feet

step-by-step explanation:

left be aligning the decimal points is required to not required see the number of digits to the right

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

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
