Answer:
The answer to your question is No
Step-by-step explanation:
To answer this question use the Vertical line test. This test states that if we draw a vertical line and intercepts the function only in one point it is a function.
It the vertical line intersects the graph in two or more points, it is not a function.
See the picture below
The graph given is not a function because the vertical line crosses the graph in three points.
Answer:
Step-by-step explanation:
The first step to do is make a single triangle from the problem. That triangle can be BDH. We do still need the line BE, although that can wait.
Now find the last angle of the triangle. The sum of angles of a triangle always equal 180, so we can easuly find the missing angle.
So the missing angle is 109°. Now we can find the value of x.
We can use that angle because it sits right next to x on the same line. A line is 180° at any node as long as the line continues straight, so we simply subtract the angle we just found to find x.
Now we know x is 71
