Answer:
Below in bold.
Step-by-step explanation:
C1 = 180 - C2
= 180 - (170-2x)
= 10 + 2x
So B3 = 10+2x (alternate angles).
and B2 = 90 - B3
= 90 - (10 + 2x)
= 80 - 2x.

Answer: These Lines are Parallel
Step-by-step explanation: For two lines to be parallel, they must have the same slope with different y-intercepts. Both of the lines above have a slope of 3 and differing y-intercepts of 4 and -5. Therefore, these lines must be parallel to one another.
Answer:
one sec sorry
Step-by-step explanation:
The correct answer is:
False.
Explanation:
An inscribed angle is an angle formed by two chords in a circle which have a common endpoint, which is the vertex of the angle.
This vertex does not have to be the center of the circle.
The chords that make up the sides of the angle do not have to go through the center of the circle.
Answer:
False
Step-by-step explanation:
The vertex doesn't have to be in the center of the circle.
