To find the area multiply the base by the height and then divide that number by 2. Now just solve the Equation. In this type of right triangle the sides corresponding to the angles 30-60-90 follow a ratio of 1 32.
Thus in this type of triangle if the length of one side and the sides corresponding angle is known the length of the other sides can be determined using the above ratio.
For any right triangle the square of the length of the hypotenuse equals the sum of the squares of the lengths of the two other sides. A c sina or a c cosv b c sinv or b c cosa Given angle and one leg. Enter the length of any two sides and leave the side to be calculated blank.
