WebNov 19, 2024 · This helps you assign the numbers to the right elements of the triangle. This is the side-side-angle case: you know two sides a and b, and a non-included angle B. The adjacent side to angle B, a = 75.3, is larger than the opposite side, a = 51.3, so you have to compute the height, h WebNov 13, 2015 · Having the length of one side and knowing that one angle is #90^@# is not sufficient information to determine the other angle(s).
WebTo solve this right triangle, we can use the Pythagorean theorem, which states that for any right triangle with legs of length a and b and hypotenuse of length c. c^2 = a^2 + b^2. We can plug in the values we have and solve for the missing side lengths and angle measures. c^2 = 12.3^2 + 31.6^2. c^2 = 382.29 + 998.56. c^2 = 1380.85. c = sqrt ...
