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.

The calculator will then determine the length of the remaining side, the area and perimeter of the triangle, and all the angles of the triangle. Area and Perimeter of a Triangle. 1. The small leg to the hypotenuse is times 2, Hypotenuse to the small leg is divided by 2. 2. The small leg (x) to the longer leg is x radical three. For Example-. Pretend that the short leg is 4 and we will represent that as "x." And we are trying to find the length of the hypotenuse side and the long side.To find the angle given two side lengths, you can use the following formulas: sin (θ) = opposite ÷ hypotenuse. cos (θ) = adjacent ÷ hypotenuse. tan (θ) = opposite ÷ adjacent. In a right triangle, the adjacent side to θ is the side of the triangle that forms part of the angle θ but is not the hypotenuse.b = 10, b = 10, β = 95°, γ = 30° β = 95°, γ = 30°.

Assume that angle A A is opposite side a, a, angle B B is opposite side b, b, and angle C C. 80°.9. Correct answer: 13.07. Explanation: The Pythagorean Theorem gives us a2 + b2 = c2 for a right triangle, where c is the hypotenuse and a and b are the smaller sides. Here a is equal to 5 and c is equal to 14, so b2 = 14 2 – 5 2 = 171. Therefore b is equal to the square root of 171 or approximately 13.07.

The Pythagorean Theorem. If a and b are the lengths of the legs of a right triangle and is the length of the hypotenuse, then the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. This relationship is represented by the formula: a2 + b2 = c2. Clatsop Community College. There are six common trigonometric ratios that relate the sides of a right triangle to the angles within the triangle. The three standard ratios are the sine, cosine and tangent.
