Angles c and d are acute angles of a right triangle.

given sind=5/7 , which statement is true?

cosc=2/7

cosc=5/7

cosd=7/2

cosd=5/7

The answer to your question is cos C =

Step-by-step explanation:

Data

sin D =

Formula

sine Ф =

- If sin D =

the opposite side = 5

the hypotenuse = 7

- We can find the adjacent side of angle D using the pytagorean theorem

               7² = a² + 5²

               a² =49 - 25

               a² = 24

               a =

- To find the cosine of angle C

 Cos C =

  Cos C =

                  sin D = cos C

i think the answer is d im not sure
