180 - x = r is true.
Thats the only one which is true.
Answer:
Step-by-step explanation:
Find slope. To do this you need this equation (in picture)
Then plug in the Y’s and x’s
Then you solve. That’s your slope
now you need to plug it in to slope intercept form
y=Mx+b
M=your slope
plug your slope Into M to get your final equation.
Answer:
Positive 8 3/4
Step-by-step explanation:
My way:
-1 2/3 times -5 1/4
- 1 2/3 simplifies to -5/3
-5 1/4 simplifies to -21/4
-5/3 times -21/4 is 35/4
Simplify that which is 8 3/4
(negative times negative = positive)
9x+18=90
9x=72
x=8
This is the answer for problem 10 above
Problem 11:
62+58= 120
180-120 =60
Therefore angle FEA is 60 degrees
59+ 61=120
180-120= 60
Therefore angle CHF is also 60 degrees
Rays:
EB and HD ; EA and HC are both parallel because they have equivalent degree angles
