Find angle of triangle with 2 sides

WebThe Law of Tangents is a statement involving the tangents of two angles in a triangle and the lengths of opposite sides. The Law of Tangents state: a-b/a+b = tan [1/2 (A-B)]/tan [1/2 (A+B)] ( 13 votes) jhou 9 years ago If you search the law of sines on the internet, it'll mostly give you A/sin (a) = B/sin (b) = C/sin (c). WebTo solve the triangle we need to find side a and angles B and C. Use The Law of Cosines to find side a first: a 2 = b 2 + c 2 − 2bc cosA a 2 = 5 2 + 7 2 − 2 × 5 × 7 × cos (49°) a 2 = 25 + 49 − 70 × cos (49°) a 2 = 74 − 70 × 0.6560... a 2 = 74 − 45.924... = 28.075... a = √28.075... a = 5.298... a = 5.30 to 2 decimal places
