Web25 apr. 2024 · Plug your numbers into the equation: tangent x = b/a. Your angle replaces "x" in the equation, and the "a" should be replaced by the first measurement you took, which measured the distance from where you're standing to the base of the object that you want to measure. Solve the equation for "b", by multiplying "a" by the tangent of your angle.
