Find angle of non right triangle
WebMar 19, 2012 · You can use this law to find all three angles. Alternatively, once you have one of the angles, you can find the next using the Law of Sines, which states that: sin A a = sin B b = sin C c And of course, once you have solved for two of the angles, you need only subtract their sum from 180 degrees to get the measure of the third.

Find angle of non right triangle
Did you know?
WebMar 3, 2015 · For a general, non right angle triangle, you need what is known as the Law of Cosines. This allows you to calculate the internal angles at each corner of the triangle given the lengths of each side. You can calculate the length of each side using the Pythagorean equality. The second part of your question is not clearly specified. Share WebUsing the right triangle relationships, we know that sinα = h b and sinβ = h a. Solving both equations for h gives two different expressions for h. h = bsinα and h = asin β. We then set the expressions equal to each other. bsinα = asinβ ( 1 ab)(bsinα) = (asinβ)( 1 ab) Multiply both sides by 1 ab. sinα a = sinβ b.
