I don't have a calculator with me right now but for this you need to remember SOH CAH TOA. So cos70 = 43m / H, in which case H is the hypotenuse (or line of sight). Next, you need to isolate the variable so you will multiply H to both sides, then divide cos70, giving you H = 43m / cos70. Plug this into your calculator to get the correct answer.
