WebMay 9, 2024 · Find all possible triangles if one side has length 4 opposite an angle of 50°, and a second side has length 10. Solution Using the given information, we can solve for the angle opposite the side of length 10. See Figure 10.1.14. sinα 10 = sin(50 ∘) 4 sinα = 10sin(50 ∘) 4 sinα ≈ 1.915 Figure 10.1.14 We can stop here without finding the value of α .
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. WebWith Right Triangle Trigonometry, for example, we can use the trig functions on angles to solve for unknown side measurements, or use inverse trig functions on sides to solve for unknown angle measurements. Thus, remember that we need the trig functions so we can determine the sides and angles of a triangle that we don’t otherwise know.
