Question

HEEELLLLLPPPPPPPPPP!!!


Which trigonometric ratio will not have the same value as sin A?

A. cos A

B. sin C

C. tan C

D. cos C

Answer 1

For corresponding Angles, sin of one of the angles and cos of the other angle will equal the same thing.

Answer 2

So \(\sf sin~A\) will be equal to what? @Kerie_lovee16

Answer 3

Hmmmm.. Uhh.. Im honestly not sure.. :/

Answer 4

Okay, let's say we have this triangle:

The same is true for here..so what's your answer going to be?

Answer 6

Oh, nevermind..that's not what it's asking..

Answer 7

ohh..

Answer 8

Btw, if you're seeing those question marks, you can reload the page.

Answer 9

So looking at this we know that \(\sf sin(A) = sin(C)\) because both angles are \( \sf 45^o\).

Answer 10

Yeahh

Answer 11

So \(\sf sin(C)\) is the same as \(\sf sin(A)\), so it's not one of our choices.

Answer 12

Okay

Answer 13

Also, for corresponding angles(angles that add up to 90 degrees) cosine will be the same as sine.

Both of these angles are the same\(\sf(45^o \!)\), so \(\sf cos(A)\) and \( \sf cos(C)\) are the same thing as \(\sf sin(A)\).

Which only leaves one more choice..and what's that? @Kerie_lovee16

Answer 14

Tan C?

Answer 15

Yep!

Answer 16

Thank youu!!!

Answer 17

No problem! :D
