+130516 24) I don't see any diagram, but I think I know how to do this.
First, convert 8000 miles to feet = 8000 * 5280 = 42,240,000 ft ......this will be one leg of the right triangle
The hypotenuse will = the radius of the Earth plus the height of the tower = 42,240,000 + 1500 =
42,241,500 ft
So, d = the max effective signal range will form the other leg of the triangle =
sqrt [ 42,241,500^2 - 42,240,000^2] = about 355,981 ft = about 67.42 miles
25) This is similar to the last one
We have a right triangle.......one leg will be 8000 miles........the hypotenuse = [8000 + 155] miles =
8155 miles
And the distance from the shuttle to the horizon will form the other leg =
sqrt [ 8155^2 - 8000^2] = about 1582.4 miles
