WebSolution. This is a 30-60-90 triangle in which the side lengths are in the ratio of x: x√3:2x. Substitute x = 7m for the longer leg and the hypotenuse. ⇒ x √3 = 7√3. ⇒ 2x = 2 (7) =14. … WebFeb 24, 2024 · To solve a 30° 60° 90° special right triangle, follow these steps: Find the length of the shorter leg. We'll call this x. The longer leg will be equal to x√3. Its hypotenuse will be equal to 2x. The area is A = x²√3/2. Lastly, the perimeter is P = x (3 + √3). What are the two special triangles in trigonometry?

WebJul 18, 2012 · Hypotenuse equals twice the smallest leg, while the larger leg is sqrt (3) times the smallest. 30-60-90 Right Triangles. WebIf the sides were in proportion to the angles, then the hypotenuse (the side opposite the 90 degree angle) would be triple the side opposite the 30 degree angle. The sides would be 1, 2, 3 or 2, 4, 6, etc. This is clearly impossible since the third side has to be shorter than the sum of the other 2 sides, since the shortest side is a straight line.
WebSep 14, 2016 · The longer leg must, therefore, be opposite the 60° angle and measure 6 * √3, or 6√3. We can see that this must be a 30-60-90 triangle because we are told that this is a right triangle with one given measurement, 30°. The unmarked angle must then be 60°. Since 18 is the measure opposite the 60° angle, it must be equal to x√3.
