Find the cos sin and tan of 28 degrees in terms of the variables x, y, and k.

Step-by-step explanation:

For this problem, k is the hypotenuse, x is the side adjacent to 28, and y is the side opposite 28.

I would remember SOH CAH TOA.

S - Sine

O - Opposite

H - Hypotenuse

For this, it shows that the sine of the angle is opposite over hypotenuse. Therefore, y/k.

C - Cosine

A - Adjacent

H - Hypotenuse

For this, it shows that the cosine of the angle is adjacent over hypotenuse. Therefore, x/k

T - Tangent

O - Opposite

A - Adjacent

For this, it shows that the tangent of the angle is opposite over adjacent. Therefore, y/x

only 10/60 isn't equivalent

hope this : )

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
