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).

WebJan 26, 2024 · We can use two different methods to find our missing angle: How to Find the Angle of a Triangle. Subtract the two known angles from 180°: 180°-37°=143° 180° − 37° = 143°. 143°−24°=119° 143° − 24° = 119°. c=119° c = 119°. Plug the two angles into the formula and use algebra: a + b + c = 180°. 37°+24°+c=180° 37° + 24 ... WebLet's find angle A first: cos (A) = (b 2 + c 2 − a 2) / 2bc cos (A) = (6 2 + 7 2 − 8 2) / (2×6×7) cos (A) = (36 + 49 − 64) / 84 cos (A) = 0.25 A = cos -1 (0.25) A = 75.5224...° A = 75.5° to one decimal place.
