Answer 1

What question are they asking?

Answer 2

The ratio of sin b to sin B is equal to tan B.
a)cos b & a)cos B
b)sin a b)sin A
c)Cos A c)cos A

Answer 3

??

Answer 4

can you post a screenshot of the full question?

Answer 5

ok I see now. Thanks.

Answer 6

What do you think?

Answer 7

what are the options for the first drop down box?

Answer 8

The ratio of sin b to sin B is equal to tan B.
a)cos b & a)cos B
b)sin a b)sin A
c)Cos A c)cos A

Answer 9

so the first drop down box has

cos B, sin A, and cos A

right? or no?

Answer 10

I'm about to do them over I had error

Answer 11

ok I'll be right back

Answer 12

ok hopefully you're learned in your lesson/lectures somewhere that

tan = sin/cos

this is one of the many trig identities

Answer 13

so this means

\[\Large \tan(x) = \frac{\sin(x)}{\cos(x)}\]

\[\Large \tan(B) = \frac{\sin(B)}{\cos(B)}\]

so tan(B) is the ratio of sin(B) to cos(B)

Answer 14

Thank You!

Answer 15

you're welcome
