Question

I WILL GIVE YOU 40 POINTS AND THE HIGHEST ANSWER. YOU HAVE TO DO WHAT THE STEPS SAYS IN ORDER TO GET EVERYTHING

Answer 1

This is a 30-60-90 triangle, in which the side opposite of the 90 degrees is the longest side (2), the side opposite of the 60 degrees is the √3 (2√3 in this case), and the last side (opposite of the 30 degrees) is the (1)

2√3/√3 = 2

So the side opposite  of the 30° = 2

a) the width is 2 miles

The length of the side walk is 2(a)
a = 2

2(2) = 4

b) The length of the sidewalk is 4 miles

hope this helps
