Webx = O A Step 4. Solve the equation Once we have picked our tool (here the tan function), insert the known values, and the unknown x : tan ( 40 ° ) = x 350 We want to isolate x on one side so we multiply both sides by 350: 350 tan ( 40 ° ) = x Using a calculator*, you will see that tan40° is 0.8391 so: x = 350 × 0.8391 which comes out to 293.69: x = 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.
