WebMar 10, 2024 · Using area and one side for right triangle trig calculation. If you know a a or b b, use the right triangle area formula that relates the base ( b b) to the height ( a a) and solve for the unknown side: Given a: b = 2 \times \text {Area}/a b = 2× Area/a; and. Given b: a = 2 \times \text {Area}/b a = 2×Area/b. WebEasier Version For Angles. We just saw how to find an angle when we know three sides. It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c 2 = a 2 + b 2 − 2ab cos(C) formula). It can be in either of these forms: cos(C) = a 2 + b 2 − c 2 2ab. cos(A) = b 2 + c 2 − a 2 2bc. cos(B) = c ...
