Answer:
Part A:
1, 4, 5, and 8 = 55 degrees.
3, 2, 6, and 7 = 125 degrees.
Part B:
I know that angle 1 is 55 degrees so angle 7 would be 125.
I know that angle 1 is 55 and to get angle 2, both angles should add up to 180 so 180 - 55 is 125, that is how I find angle 2 = 125 degrees.
Step-by-step explanation:
This is what I wrote, I hope it helps and tell me if I am wrong but I think it is right.
Have a Meowgical day!
I'm assuming that you mean
because if you meant
then u would simplify and you couldn't make it the subject.
Under this assumption, we start with
We multiply both sides by 
We expand the left hand side:
We move all terms involving u to the left and all terms not involving u to the right:
We factor u on the left hand side:
We divide both sides by 
Answer:b
10 to 20 is 10 and 80 to 60 is -20 so it’s -20/10 which is -2
Answer:
c
Step-by-step explanation:
The limit exists because it's continuous since they equal each other
when x approaches zero.
Substitute both expressions with x=0 and both of them will equal 2, so the limit should be 2.
6x - 28 = 4x + 20
2x - 28 = 20
2x = 48
x = 24
6(24) - 28 = 116
mRS = 116°
