Look at the figure below:

if sin y° = 9 divided by c. and tan y° = 9 divided by d. ,what is the value of cos y°?

a.) cos y° = 9c
b.) cos y°=c divided by d.
c.) cos y°=d divided by c.
d.) cos y° = 9d

answer: option c.

step-by-step explanation:

remember the following trigonometric identities:

then, knowing that:

you can identify that the angle is y°, the adjacent side is and the hypotenuse is .

then, you have to substitute them into   . so you get:

(which matches with the option c).

the answer is:

c)

since it's a right triangle we can find the correct answer using the following formulas:

where,

x is the base of the triangle

y is the height of the triangle

h is the hypotenuse of the triangle

so, using the given information we have that:

where:

also, we know that:

where,

therefore,

the correct answer is

c)  

have a nice day!

step-by-step explanation:

just count the values of x & y of the vertex of the graph and see how many units in the x and y direction will get you from the f(x) graph to the f(x) graph
