Y=2x + 15
y = 11-x
In order to solve for y add/subtract the x terms to the other side
So I took the test and my teacher said to label all of the degrees so
angle 1,3,5,7,9,11,13,15 all = 95 degrees
angle 2,4,6,8,10,12,14,16 all = 85 degrees
I know 1 and 3 are vertical angles
3 and 8 are same side interior angle
4 and 14 alternate interior angles
6 and 12 are alternate exterior angles
13 and 9 are corresponding angles
4 and 7 are same side interior angles
I believe these are correct but you might want to double check with some other source
Answer:
z= -160
Step-by-step explanation:
452.16 = 3.1416 r^2
r^2 = 452.16 / 3.1416
r^2 = 143.93
r = 11.997
C = 2 (3.1416) (12) =75.38 m
Ok so this is a Pythag question...
So the first step would be A squared plus B squared equals C squared
Your A squared would be 12
You do not have B squared value yet
Your C squared Would be 16
So your equation is 12 squared plus B squared equals 16 squared
Simplified that would be 144 plus B squared equals 256
Subtract 144 from both sides and you get 112 equals B squared so do that dividing symbol thing on both sides and you get 10.58 equals c
C= 10.58
