They’re all adding 5, so 18+5=23
So I think 23
The train because it travels at 63 mph while the bus is 59 mph
The given expression is

In this expression we have to solve for U.
First we have to get rid of E from the denominator, and for that, we have to multiply both sides by E, that is

Now we need to get rid of 3, and for that, we have to divide both sides by 3, that is

Answer:
y=-x
Step-by-step explanation:
The easiest one to use would be y=-x because it is parallel to the given line and goes through the stated point.
We have to break each degree in terms of 90
A) 
Which is in third quadrant, therefore sine is negative hence

B) 
Which is in third quadrant, therefore cosine is negative hence

C) 
Which is in third quadrant, therefore tangent is positive hence

D) 
Which is in third quadrant, therefore cosec is negative hence
not defined
E)
Which is in third quadrant, therefore secant is negative hence

F) 
Which is in third quadrant, therefore tangent is positive hence
not defined
Hence only
and
have value -1
Hope this will help
