Question

(104sin17 x cos17)/sin34

Answer 1

(104 *sin17 * cos17) / sin34 = (104 *sin17 * cos17) / (2* sin17 * cos17) = 52

Ответ  52

Answer 2

104sin17 * cos17       52 * 2 sin17 * cos17     52 * sin 2 * 17       52 * sin 34

---------------------- = ----------------------- = ----------------- = --------------------- = 52

           sin34                     sin34                        sin34                  sin34
