Step-by-step explanation:
Data
length = 16 ft
angle = 71°
Opposite side = ?
Process
1.- To answer this question use trigonometric functions.
The trigonometric function that relates the Opposite side and the hypotenuse is sine.
2.- Write the trigonometric function
sin Ф = Opposite side / hypotenuse
3.- Substitution and result
sin (71) = x / 16
The common denominator is 28
The mean is the average. Add all the numbers together, then divide by the quantity of numbers in the data set.
1040 / 13 = 80
