Triangle side length formula math. This calculator calculates for the length of one side of a right triangle given the length of the other two sides. Since we know 1 side and 1 angle of this triangle we will use sohcahtoa step 2 set up an equation using the sine cosine or tangent ratio since we want to know the length of the hypotenuse and we already know the side opposite of the 53 angle we are dealing with sine. For a given angle θ each ratio stays the same no matter how big or small the triangle is. C a b.

Sine cosine and tangent often shortened to sin cos and tan are each a ratio of sides of a right angled triangle. Enter the length of any two sides and leave the side to be calculated blank. So when you multiply c by itself the result is 25. Calculate the length of a hypotenuse if given legs and angles at the hypotenuse c.

3 2 b 2 5 2 9 b 2 25 b 2 16 b 4. Plug those into the appropriate places in the pythagorean equation. Therefore take the square root of both sides to find. So if you know the lengths of two sides all you have to do is square the two lengths add the result then take the square root of the sum to get the length of the hypotenuse.

Sine cosine and tangent. Sides a and b are the perpendicular sides and side c is the hypothenuse. A right triangle has two sides perpendicular to each other. C a b the hypotenuse is the longest side of a right triangle and is located opposite the right angle.

Here s how to use the pythagorean theorem to find the length of the hypotenuse. Side leg of a right triangle. As you can see it is pretty simple to use the pythagorean theorem to find the missing side length of a right triangle. The ratio of the length of a side of a triangle to the sine of its opposite angle is constant.

Where a and b are two sides of a triangle and c is the hypotenuse the pythagorean theorem can be written as. This formula allows you to find the hypotenuse of a triangle given only the lengths of the legs. Digit 1 2 4 6 10 f.
