WEB2 days ago · Using trigonometry. If you are familiar with the trigonometric basics, you can use, e.g., the sine and cosine of 30° to find out the other sides' lengths: a/c = sin(30°) = 1/2 so c = 2a. b/c = sin(60°) = √3/2 so b = c√3/2 = a√3. Also, if you know two sides of the triangle, you can find the third one from the Pythagorean theorem.

WEBMay 22, 2021 · A 30-60-90 is a scalene triangle and each side has a different measure. Since it’s a right triangle, the sides touching the right angle are called the legs of the triangle, it has a long leg and a short leg, and the hypotenuse is the side across from the right angle. In this lesson we’ll look at how.

WEBThe ratio of the side lengths of a 30-60-90 triangle are: The leg opposite the 30° angle (the shortest side) is the length of the hypotenuse (the side opposite the 90° angle). The leg opposite the 60° angle is of the length of the hypotenuse. The hypotenuse is twice the length of the shortest side.

https://www.voovers.com/geometry/30-60-90-triangle/
WEBINTRODUCING. 30 60 90 Triangle Rules. To fully solve our right triangle as a 30 60 90, we have to first determine that the 3 angles of the triangle are 30, 60, and 90. To solve for the side lengths, a minimum of 1 side length must already be known. If we know that we are working with a right triangle, we know that one of the angles is 90 degrees.
