Trigonometry can be used to measure objects. This can be done using sin, cos, and tan. You can create a triangle using the object that you want to find the height of as one of the sides. You can stand a certain distance back from the object and that can be your other side and that’s the side you know the length of. Using that side and the angle from the end of the side on the ground, you can find the height of the object.
