In $△ A B C, ∠ B = 90^{o}, A B = 3 c m a n d B C = 4 c m$ then match the column

Open in App

Solution

$I n △ A B C, A C = \sqrt{3^{2} + 4^{2}} = 5 c m sin C = \frac{A B}{A C} = \frac{3}{5} cos C = \frac{B C}{A C} = \frac{4}{5} tan A = \frac{B C}{A B} = \frac{4}{3} sec A = \frac{A C}{A B} = \frac{5}{3}$
