How do you use sine in math?
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
How do you calculate the perimeter of a triangle?
-- Measure or calculate the length of one side. -- Measure or calculate the length of another side. -- Measure or calculate the length of the only remaining side. -- Add the three numbers. The sum is the perimeter of the triangle.
How do you calculate the area of an triangle?
length times width squared
What if youknow one length of a right triangle and not the other leg or hypotenuse?
If you also know the measure of one of the acute angles, you can calculate all of the missing pieces. But if you only know the length of the one leg and nothing else, then you don't have enough information to calculate anything else.
How do you calculate the length of a right angled triangle using the sine formulae?
The answer depends on what other information you have about the triangle.
