D = 5/6 sqrt(h)
7 = 5/6 sqrt(h)
42/5 = sqrt(h)
h = (42/5)^2 = 1,764/25 = 70.56
The height of the mast is 70.56 miles
E is the answer. Since it’s a 45 45 90 triangle the rules are the hypotenuse is equal to x squareroot of 2 while the two other sides are just equal to x. If Xv2= 32 then the two sides (x) must be equal to 16v2
