In RT △ ABC, ∠ C = 90 °, a right triangle is solved by the following conditions (1) If we know that a = 4 times radical 3, B = 2 times radical 3, then C =? (2) If a = 10, C = 10 times the root 2, then ∠ B =? (3) If C = 20 and a = 60 ° are known, then a =? (4) If B = 35 and a = 45 ° are known, then a =?

(1) If a = 4 times root 3, B = 2 times root 3, then C = 2 √ 15
(2) If a = 10, C = 10 times root 2, then ∠ B = 10
(3) : given C = 20, ∠ a = 60 °, then a = 10 √ 3
(4) If B = 35 and a = 45 ° are known, then a = 35
