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. …
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. how to remove old boat letteringWebThe sides of a 30-60-90 right triangle lie in the ratio 1:√3:2. The side lengths and angle measurements of a 30-60-90 right triangle. Credit: Public Domain.
