WHERE TWO SIDES ARE KNOWN
Now you try it! THREE MORE IMPORTANT KEYS: sin -1 cos -1 tan -1 IF TWO SIDES ARE KNOWN SOLVE FORMULAS A & B D tan -1 (A ÷ B) A & C D sin -1 (A ÷ C) B & C D cos -1 (B ÷ C) A & B E tan -1 (B ÷ A) A & C E cos -1 (A ÷ C) B & C E sin -1 (B ÷ C) Now you try it÷! (Round answer to nearest tenth place. 00.0) 1. If B = 3.464 and C = 4.000 what is D = __________ 2. If B = 3.464 and A = 2.000 what is D = __________ 3. If A = 2.000 and C = 4.000 what is D = __________ 4. If B = 3.464 and C = 4.000 what is E = __________ 5. If B = 2.000 and A = 2.000 what is D = __________ 6. If A = 3.500 and B = 3.800 what is D = __________ 7. If A = 3.500 and B = 3.800 what is E = __________ (
