Webb4 juli 2024 · The side opposite the 30° angle is half of a side of the equilateral triangle, and hence half of the hypotenuse of the 30-60-90 triangle. The length of the remaining side follows via the Pythagorean Theorem. “And I take the triangle COY with angles 30-60-90. Since OC = 1, then OY = (√3)/2, and CY = 1/2. Then I take triangle BCY. WebbThe area T of any triangle can be written as one half of its base times its height. Selecting one side of the triangle as the base, the height of the triangle relative to that base is computed as the length of another side times the sine of the angle between the chosen side and the base. university writing center ncat https://gftcourses.com
