The grams to cups calculator converts between cups and grams. = 45/20 [1] If radians are selected as the angle unit, it can take values such as pi/3, pi/4, etc. Their angles are also typically referred to using the capitalized letter corresponding to the side length: angle A for side a, angle B for side b, and angle C (for a right triangle this will be 90) for side c, as shown below. Find the length of the hypotenuse of the triangle. To find the longest side we use the hypotenuse formula that can be easily driven from the Pythagoras theorem, (Hypotenuse) 2 = (Base) 2 + (Altitude) 2.

In this type of right triangle, the sides corresponding to the angles 30-60-90 follow a ratio of 1:3:2. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Knowing this ratio comes in especially handy when your test or homework question gives you the side lengths in terms of variables instead of integers.

Because it is a special triangle, it also has side length values which are always in a consistent relationship with one another. In an isosceles right triangle, the two legs are of equal length. If you are given the length of the shortest leg (opposite the 30-degree angle,) simply multiply the leg length by 2 to find the length of the hypotenuse. In this particular case, the two legs of our triangle are x 2 and x, since the legs are the two smallest sides; therefore, we can say that a = x 2, and b = x. Plugging this value into the area formula, we get area = 253/2 21.65.
