Let be the center of Earth, F be the satellite, and H be a point on the horizon. FH is tangent to ñ at H, so FH H because a line tangent to a circle is perpendicular to the radius at the point of tangency. This means ΔHF is a right triangle. Use the Pythagorean Theorem to find the length of FH. Step 3 Solve. F = 50 mi F = + F = 4, = 4050 mi F 2 = FH 2 + H 2 Pythagorean Theorem (4,050) 2 = FH 2 + (4, 000) 2 Substitute 4,050 for F and 4,000 for H. 402, 500 FH 2 Subtract (4, 000) 2 from both sides. 634 mi FH Take the square root of both sides. orrect! Take the square root of this result. Round to the nearest mile, not nearest ten miles. dd 50 mi to 4,000 mi to obtain the hypotenuse of a right triangle. Using 4,000
