WebOct 28, 2024 · To solve it, add 1 to both sides and divide by 3: tan² ( B /2) = 1/3. and then take square root of both sides: tan ( B /2) = ±√ 1/3 = ±√ 3 /3. It’s important to remember to use the plus-or-minus sign ± when taking the square root of both sides; otherwise you could overlook some solutions. Step 3. Solve for the angle. WebIn your solving toolbox (along with your pen, paper and calculator) you have these 3 equations: 1. The angles always add to 180°: A + B + C = 180° When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue.
