What's the correct label for an angle with its vertex at point y that passes through point x on one side of the angle and point z on the other side of the angle? a. ∠yzx b. ∠xyz c. ∠x d. ∠zxy

The correct answer option is B. ∠XYZ.

Step-by-step explanation:

In geometrical terms, an angle is the figure which is formed by two rays which are called the sides of the angle.

Here, for the described situation for a triangle XYZ, Y is the vertex with the side rays or sides of the angle YX and YZ.

Considering the sides of the angle, you can name the angle as either ∠XYZ or ∠ZYX or simple ∠Y without mentioning any side rays.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
