There are three acute angles in an acute triangle. In geometry, triangles are considered as 2D closed figures with three sides of the same or different lengths and three angles with the same or different measurements. To find the missing information with the Law of Sines, follow these steps: Determine the measure of the third angle. I'm not a mathematician, but it seems to me that no one can find the missing sides (note the plural: "sides") of a triangle by having just one -- or none. Hold down Left or Right ALT or CTRL keys to lock a side or angle. Setting b and c equal to each other, you have this equation: Cross multiply: Divide by sin 68 degrees to isolate the variable and solve: State all the parts of the triangle as your final answer. To find angles we can use what are known as inverse trigonometric functions. Assume we want to find the missing side given area and one side. Oblique Triangle Solutions Calculator & Equations.
