The ratio of the two sides = 8:8√3 = 1:√3. this indicates that the triangle is a 30 60 90 triangle. we know that the hypotenuse is 2 times the smallest side. thus, the hypotenuse is 2 × 8 = 16 units. answer: hypotenuse = 16 units. example 2: a triangle has sides 2√2, 2√6, and 2√8. find the angles of this triangle. And because this is a 30 60 90 triangle, and we were told that the shortest side is 8, the hypotenuse must be 16 and the missing side must be $8 * √3$, or $8√3$. our final answer is 8√3. the take aways. remembering the rules for 30 60 90 triangles will help you to shortcut your way through a variety of math problems. but do keep in mind.
The ratio of the side lengths of a 30 60 90 triangle is 1 ∶ √3 ∶ 2. this means that if the shortest side, i.e., the side adjacent to the 60° angle, is of length 𝑎, then the length of the side adjacent to the 30° angle is 𝑎√3, and the length of the hypotenuse is 2𝑎. in this case we have 𝑎√3 = 15 ⇒ 𝑎 = 5√3. When writing about 30 60 90 triangle, we mean the angles of the triangle, that are equal to 30°, 60° and 90°. assume that the shorter leg of a 30 60 90 triangle is equal to a. then: the second leg is equal to a√3; the hypotenuse is 2a; the area is equal to a²√3 2; and. the perimeter equals a (3 √3). the 30 60 90 triangle formulas. Learn how to solve 30 60 90 triangles using a formula for the sides. i'll show you how to find the missing sides of a 30 60 90 right triangle using the rela. Substitute the value of the shorter leg in the formula. c = 2 (a) c = 2 (4) c = 8 units. according to the 30 60 90 triangle theorem, the longer leg is the square root of three times as long as the shorter leg. multiply the measure of the shorter leg a = 4 by √3. b = √3 (a) b = √3 (4) b = 4√3 units.

With 45 45 90 and 30 60 90 triangles you can figure out all the sides of the triangle by using only one side. if you know one short side of a 45 45 90 triangle the short side is the same length and the hypotenuse is root 2 times larger. if you know the hypotenuse of a 45 45 90 triangle the other sides are root 2 times smaller. Aboutabout this video. transcript. a 30 60 90 triangle is a special right triangle with angles of 30, 60, and 90 degrees. it has properties similar to the 45 45 90 triangle. the side opposite the 30 degree angle is half the length of the hypotenuse, and the side opposite the 60 degree angle is the length of the short leg times the square root.
