WebMar 10, 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.
