### 4 Ways to Construct an Isosceles Triangle - wikiHow

Mar 29, 2019 · Thus, each 45° angle in each smaller right triangle has an opposite side and an adjacent side of length 30 and a hypotenuse of x (the length you're trying to find). The sine (and cosine) of each 45° angle is 0.707. Therefore, 0.707 = 30 / x. x = 30 / 0.707 = 42.4. That's the length of each of the two equal sides of the big triangle.
