Answer:
I think it 6 is the answer I don't know I'm not in middle school
Answer:
A= 150°
B=30°
C=150°
Step-by-step explanation:
Since a line is 180°, you can write an equation for C. C+30°=180° , from here use algebra to find C. The value of C will be 150°. When the value of C is 150° , since they're supplementary angles, the value of A will also be 150°.
Important thing to note:
The value of all these angles combined together is 360°.
Answer:

Step-by-step explanation:
To solve this problem, first you have to use the slope formula of
.
y2= (-7)
y1=6
x2=4
x1(-6)
Solve.

Therefore, the correct answer is -13/10.
Its 0.5. Which would be in fraction form 5/10 meaning its 5 tenths.
