2)
$ 97.125
Step-by-step explanation:
1)
5 days at $69.00 a day.
It is given that the earning of one day is: $ 69
Hence, the earning of 5 days will be:
Hence, the value of is 345.
2)
3.5 days at $27.75 a day .
It is given that the earning of one day is: $ 27.75
Hence, the earning of 3.5 days will be:
Hence, the value of is 97.125.
Answer:
.
Step-by-step explanation:
Here, I've attached a picture of the triangle that accompanies this explanation.
cot = = =
Now view the triangle.
PS. Angle theta will have a coordinate of (-, +) because it is in quadrant II.
sin of the angle would be opposite/hypotenuse, so sin =
cos of the angle would be adjacent/hypotenuse, so cos =
tan of the angle would be opposite/adjacent, so tan =
