Question

Найти sina если tg a= -7/24

Answer 1

Решение 1) tgA = ВС/ АС = 7/24 тогда ВС = 7х и АС = 24х 2) по теореме Пифагора находим гипотенузу АВ АВ² = 49х² + 576х² = 625х² АВ = 25х 3) Sin A = ВС/АВ = 7х/ 25х = 7/25 Ответ Sin A = 7/25 = 0,28

Answer 2

Finding the value of sina when tg a = -7/24

To find the value of sina when tg a = -7/24, we can use the trigonometric identity:

tg a = sina / cosa

Rearranging the equation, we have:

sina = tg a * cosa

Now, let's substitute the given value of tg a = -7/24 into the equation and solve for sina.

sina = (-7/24) * cosa

Unfortunately, the search results provided do not contain the specific value of cosa or any additional information that would allow us to calculate the value of sina. Therefore, we cannot determine the exact value of sina based on the given information.

If you have any additional information or if there is anything else I can assist you with, please let me know!
