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

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
