Four more than twice of x
Twice of x can be written as 2x
Four more than 2x
Four more can be written as + 4
We get 2x + 4

Answer:
∠ABE and ∠CBD
∠ABC and ∠EBD
Step-by-step explanation:
we know that
<u>Vertical angle</u>s are a pair of opposite and congruent angles formed by intersecting lines
In this problem we have that
∠ABE=∠CBD ------> by vertical angles
∠ABC=∠EBD ------> by vertical angles
therefore
The angles that are vertical angles are
∠ABE and ∠CBD
∠ABC and ∠EBD
