Question 1
angle 1=angle 3
angle 3=37
therefore angle 1=37
Answer:
Step-by-step explanation:
∠y=142°
∠x=180-142=38°
Answer:
X = -5
Explanation:
You can graph a vertical line by assigning a value to x. By assigning it to the value -5, it will pass through the point -5, as well as all y values.
Answer:
7 units
Step-by-step explanation:
When you reflect a point (x, y) across the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign: it becomes (-x, y).
Thus, if a point A, say, (-7, 5) is seven units to the left of the y-axis, its reflection A' will be the same distance to the right, at (7,5).
In the image below, Point A is seven units to the left of the y-axis. Its reflection, Point A', is seven units to the right of the axis.
