Question

Look at the figure:

An image of a right triangle is shown with an angle labeled x.

If tan x° = a divided by 4 and cos x° = 4 divided by b what is the value of sin x°?

sin x° = 4b
sin x° = b divided by a
sin x° = 4a
sin x° = a divided by b

Answer 2

Do you know "Soh Cah Toa?"

\[Sine = \frac{ opposite }{ hypotenuse }\]
\[Cosine = \frac{ Adjacent }{ Hyotenuse }\]
\[Tangent = \frac{ Opposite }{ Adjacent }\]

Answer 3

yes

Answer 4

tan x= a/4 , cos x = 4/b

sin x/cos x = tan x

sin x = tan x * cos x

sin x = a/4 * 4/b simplify it

Answer 5

Cool! So it says

\[Tangent = \frac{ a }{ 4 }\]
\[Cosine = \frac{ 4 }{ b}\]

So place those on the triangle

Answer 6

im so confused XD

Answer 9

opposite and adjacent depends on what angle we are looking at
