Note that the , and keys automatically open a bracket for you. 2. To double check, you can say is 27/60 equal to 0.45? For example, the ability to compute the lengths of sides of a triangle makes it possible to find the height of a tall object without climbing to the top or having to extend a tape measure along its height. So you have a proportion: 45/100 = ?/3600. If you very carefully construct a right triangle with an angle of 47 degrees, you may be able to get some fairly accurate measurements of the sides and see that this 47-43-90 right triangle has sides measuring about 0.7314-0.6820-1 (or some multiple thereof).
