Part 2)
Step-by-step explanation:
we have that
The cosine of angle theta is negative and the tangent of angle theta is positive
That means that the sine of angle theta is negative
step 1
Find
we know that
we have
substitute
square root both sides
Remember that
In this problem the sine of angle theta is negative
so
step 2
Find
we know that
we have
substitute the given values

i wish i could help but im confused also
Step-by-step explanation:
...
Area of a triangle = 1/2 b•h
A = 1/2 b • h
A = 1/2 (10 cm • 9 cm)
A = 1/2 (90 cm^2)
A = 45 cm^2.
Let us assume the number of cars parked after which John will start earning more than his fixed weekly salary = x
The fixed weekly salary of John = $300
The fee that John gets for parking each car = $5
Then we can get the equation as
5x = 300
x = 300/5
= 60
So from the above deduction we can see that John will earn the equal amount of his weekly pay after he parks 60 cars. Then it becomes obvious that parking car number 61, John will start earning more than what he gets as his fixed weekly salary. I hope you have understood the described method.
