Answer:
- ∠XVR = 125°
- ∠RVS = 55°
- ∠WVS = 125°
Step-by-step explanation:
Any angles on opposite sides of the intersection point of crossing lines are "vertical" angles, and they have identical measure.
Any angles along the same side of the same line are "linear" angles, and they are supplementary (add to 180°).
The angles inside a triangle add to 180°.
Using these relationships, work from the given information to find the rest of the angles.
Answer:

Step-by-step explanation:
We are required to simplify the following expression;

Using the properties of radicals;

The expression can be re-written as;

Now;

Answer:
a 90° clockwise rotation about the origin and then a reflection a cross the x-axis
Answer:
90 degrees
Step-by-step explanation:
Angle DMC is vertical angles with angle AMB. Vertical angles always have the same degree measure.
Since angle AMB = 90 degrees, we know that because DMC = AMB, then angle DMC is also 90 degrees.
Hope this helps!
