Answer:
D
Line segments are congruent due to the side-angle-side congruence postulate.
Step-by-step explanation:
DC is the perpendicular bisector of line AB, this mean that DC divides AB at 90 degrees into two equal parts at point E. Hence:
AE = BE
Also DE ≅ DE (reflexive property of congruence)
Also ∠AED = ∠BED = 90° (perpendicular bisector)
We can therefore say that triangle AED and triangle BED are congruent according to the side-angle-side congruence theorem. Therefore line AD = line BD
Answer:
the equation will be:

solving the equation we get x=8
Option B is correct.
Step-by-step explanation:
We need to write equation for this sentence:
The difference between a number and five equals three.
Let number = x
So, the equation will be:

Now, solving the equation to find value of x

Adding 5 on both sides

So, solving the equation we get x=8
Option B is correct.
