If the hypotenuse is 50 cm long, find the area of the triangle. Then, another side is x+4.The length of the opposite side=4+6=10. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. The hypotenuse is the longest side of the triangle, and its also very easy to find using a couple of different methods.

Include, what criteria will be used and what feedback. The variable "c" will always be assigned to the hypotenuse, or longest side. Choose one of the other sides to be a, and call the other side b (it doesn't matter which is which; the math will turn out the same). Then copy the lengths of a and b into the formula, according to the following example: 15 B. How long is the diagonal of the new rug she places in her classroom?
