Question

I need some help with this! I know about the trig identitys and stuff like that, but I just get a little confused on how to apply sometimes.

Answer 1

we have that

Let

x ------> the distance in miles from a point on the ground (the red line)

In the right triangle of the figure

sin(6.5)=7,000/x

solve for x

x=7,000/sin(6.5)

using a calculator

x=61,835.70 ft

Convert to miles

Remember that

1 mile=5,280 ft

so

61,835.7 ft=61,835.7/5,280=11.71 miles

therefore

the answer is 11.71 miles
