To define a perpendicular rays, we first define a ray.
A ray starts from one point and extend it to form one direction.
If two lines or rays or line segments intersect at right angle (90°), then they are perpendicular.
In particular, Perpendicular rays are rays that intersect to form a right angle.
Four right angles are formed in the perpendicular rays.
Answer: no
Step-by-step explanation:
Answer:
80 degrees
Step-by-step explanation:
one half of the circle makes a straight line and that will equal 180 degrees so 60+45=105
180-105=80
so the missing angle is x=80
Answer:

Step-by-step explanation:
1. Regroup terms.

2. Add 1 to both sides.

3. Simplify 3x + 3 + 1 to 3x + 4.

4. Subtrect 3x from both sides.

5. Simplify 4x - 3x to x.

Therefor, the answer is, x = 4.
