True or false: Vertical angles are the top and bottom angles of the four angles formed by two intersecting lines.
1 answer:
Answer: True
Step-by-step explanation:
- When two lines intersect each other at the vertex (known as point of intersection), four angles are formed .
- The angles that are opposite from each other are known as a pair of vertical angles and they are always equal.
- So, left and right angles must be equal (i.e. ∠3=∠4) and top and bottom angles are equal (i.e. ∠1=∠2) .
Hence, the given statement is correct .
so, the answer is "True".

Answer:
22.2 ft²
Step-by-step explanation:
The area (A) of a sector is calculated as
A = area of circle × fraction of circle
= πr² ×
= π × 7.13² ×
= ≈ 22.2 ft² ( nearest tenth )
