Question

If tan x = .67 and cos x = .83, what is sin x?
Answer

.33

.43

.56

.67

Answer 1

use the relation,
tan x = sin x / cos x

Answer 2

soo .67 /.83 ?

Answer 3

no,
since tan x = sin x/ cos x
then, sin x = tan x cos x = ... ?

Answer 4

soo multiply?

Answer 5

yes!

Answer 6

\(\bf tan(x) = \cfrac{sin(x)}{cos(x)}\\ \quad \\
0.67 = \cfrac{sin(x)}{0.83}\)

Answer 7

After i multiply do i round it ?
