Question

Триганометрия 6 tg a, sin a = 24/25 × a ,a - ||

Answer 1

tg a = sin a/cos a

cos^2 a = 1 - sin^2 a

cos^2 a = 1 - (24/25)^2

cos^2 a = 1 - (576 / 625)

cos^2 a = 49/625

cos a = 7/25   или   cos a = -7/25  

tg a = 24/25  : 7/25 = 24*25/25*7 = 24/7  

tg a 24/25  :(-7/25)  = -24/7

Answer 2

It seems there might be a misunderstanding or a typo in your question. It looks like you're providing an equation involving trigonometric functions, but there's a symbol "||" at the end of your expression for 'a' that seems out of place. Additionally, the equation format is not entirely clear.

If you could clarify the equation or provide more details, I'd be happy to help you solve it or provide more information about trigonometry. Please check the equation and ensure that all the terms are correctly represented.
