How do I find the angle of a triangle given two sides?

Since we know all three sides, we have to use the law of cosines to find the angle at A. a 2 = b 2 + c 2 - 2bc cos A 10 2 = 7 2 + 5 2 - 2 (7) (5) cos A 100 = 49 + 25 - 70 cos A 100 = 74 - 70 cos A 70 cos A = 74 - 100 70 cos A = -26 cos A = -26 / 70 A

Finding an Angle Given Two Sides.mp4

For a triangle with sides a, b, and c, if a and b are known and C is the included angle (the angle between the sides), C can be worked out with the cosine rule. The formula is as follows: c = a2 + b2 - 2 ab cos C When should the
