Web10 mrt. 2024 · To solve a right triangle using trigonometry: Identify an acute angle in the triangle α. For this angle: sin (α) = opposite/hypotenuse; and. cos (α) = adjacent/hypotenuse. By taking the inverse trigonometric functions, we can find the value of the angle α. You can repeat the procedure for the other angle. WebThe proof is that if you mirror the triangle on the 30 degrees side, you get a bigger triangle whose 3 sides are of the same length, and thus its angles are all 60.
