WebYou can use the Pythagorean Theorem on any right triangle which is what is being done. If you want to generalize, you have one leg that is the radius (r) and another that we can call b. The hypotenuse is formed by adding r+c. Thus, you get b^2+r^2= (r+c)^2. Solving for r, … WebThe radius of the coverage circle can be found using the Pythagorean theorem: r = (h + R) × tan ⁡ (10 °) where h is the orbital height, R is the radius of the Earth, and 10° is the elevation angle. Substituting the given values, we get: r = (35,800 k m + 6,371 k m) × tan ...

WebUnfortunately, tan B is the ratio of the two sides you don’t know, namely, b/a. There is more than one way to solve this problem. Here are two. Method 1. Take the equation 1.2 = tan B = b/a, to get a relation between a and b, namely b = 1.2a. The Pythagorean theorem then gives 6.25 2 = a 2 + 1.44 a 2, from which you can determine a, and then ...
