Answer:

45

Step-by-step explanation:

Triangles equal up to 180 degrees therefore you do the following to solve this equation. So you have 80 and 55. So you add 80 to 55 and you get 135. Now you subtract 180 by 135 and that equals 45. So x=45. I will write it out as well.

55+80=135

180-135=45

x=45

To check.

80+55+45=180

Question 7 which graph represents a function
ratelena [41]

Answer:

Where are the graphs?

Step-by-step explanation:

Anyway use this method.

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.
