Answer:

x = 60°

Step-by-step explanation:

First, note that the 30° angle and Angle CGE are vertical angles; therefore, Angle CGE is also a 30° angle.

Next, note that Angles CGE and x are complementary angles; that is, they sum up to 90°.

Subtracting Angle CGE (a 30° angle) from 90° yields 60°. This is the desired answer: x = 60°

Answer:

x = 60°

Step-by-step explanation:

G= 90°

30 + 90 = 120

180 - 120 = 60

A point lies in quadrant 2. If it is rotated 180 degrees counterclockwise, which quadrant will the point come to rest?

NeTakaya

A point (a, b) in the second Quadrant, is any point where a is negative and b is positive.

For example (-3, 5), (-189, 14) etc are all points in the 2.Quadrant

Rotating a point P(x, y) in the second Quadrant 180° counterclockwise, means rotating 180° counterclockwise about the origin, which maps point P to P'(-a, -b) in the fourth Quadrant.
