Use the formula for secants in a circle. The formula for us in our situation is
x^2=239,000(239,000+8,000). Work within the parenthesis first to get
x^2=239,000(247,000). Do the multiplication now to get
x^2=5.9033*10^(10). Take the square root of that to get x = 242,967.076 miles or, according to how your answer is to be stated, 243,000 miles.
