Answer:
x = 32
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin 30 = 16/ x
Multiply each side by x
x sin 30 = 16/x * x
x sin 30 = 16
Divide each side by sin 30
x = 16/ sin 30
x = 16 / (1/2)
x = 32
1km = 1000m
1 mile = 1609 m
8045m* 1mile/1609m= 5miles
Subtract 4.5 from 20.5 and you'll have your answer which is x=16
