How to Solve a Triangle When You Know Two Angle Measures
WebIf you have a three sided polygon (a triangle) and you know the side lengths then the figure is rigid and it should be possible to find the angles. If you have a polygon with more than three sides and you know the side lengths then the figure is not rigid and the angles can vary. The relationship you are looking for is called the Law of Cosines. WebInstead, you will be expected to memorize the sines and cosines of some special angles. Other than that, either you will be allowed to use a calculator or you'll be given the values. The actual computation for cosine (angles expressed with radians, not degrees): cos x = ½ [ e^ (-i*x) + e^ (i*x)] WebThe given angle is 37 deg. We want to find the opposite angle, and are given the adjacent length, 3. So plug in our formula: tan*37=?/3. We multiply both sides by 3: 3*tan*37=?. … go to my house
