Find sides and angles of triangle

WebThe sine rule can be used to find an angle from 3 sides and an angle, or a side from 3 angles and a side. The cosine rule can find a side from 2 sides and the included angle, or an angle from 3 sides. WebTo find TY, the side you are looking for, you need to use tan. You use tan because of SOH CAH TOA, to use tan you use the opposite and adjacent which you have in the problem. Look at the 37 degree. The side across from it, or the opposite, is what you are trying to find so it will be your x or unknown value. You know the adjacent side, it is three.

WebUse the Law of Sines, sinC/c = sinB/b, to find angle A: sin (C) / 7.4 = sin (104.1°) / 15.2 sin (C) = 7.4 × sin (104.1°) / 15.2 sin (C) = 0.4722... C = 28.2° to one decimal place Find angle A using "angles of a triangle add to 180": A = 180° − (104.1° + 28.2°) A = 180° − 132.3° A = 47.7° to one decimal place So A = 47.7°, B = 104.1°, and C = 28.2° WebYou can ONLY use the Pythagorean Theorem when dealing with a right triangle. The law of cosines allows us to find angle (or side length) measurements for triangles other than right triangles. The third side in the example given would ONLY = 15 if the angle between the two sides was 90 degrees. sabots for furniture legs https://hickboss.com
