Answer:
The remaining side has a length of six units.
Step-by-step explanation:
We know that this is an Isosceles triangle because angles A and C are marked as being the same angle. So we know that AB and CB are the same length.
As we're given their lengths, we can simply equate the two, and solve for x:
So we know that the remaining side has a length of 6.

Solution:
Side-splitter theorem:
<em>If a line is parallel to one side of a triangle and the line intersects the other two sides, then this line divides those two sides proportionally.</em>
Do cross multiplication, we get
⇒ 4 × 42 = 21x
Divide by 21 on both sides, we get
⇒ 4 × 2 = x
⇒ 8 = x
Switch the sides.
⇒ x = 8
The value of x is 8.
