The value of the missing side is 4. This is solved using the Triangle Proportionality Theorem.
What is the Triangle Proportionality Theorem in simple terms?
The theorem posits that the other two sides of the triangle are divided in the same ratio if a line is drawn parallel to any one side of a triangle and touches the other two sides at two different spots.
What is the calculation that supports the above answer?
The calculation as already indicated is solved using the Triangle Proportionality Theorem.
According to the theorem,
2/7 = ?/14
? = 2/7 * 14
? = 28/7
? = 4
What is the use of the the Triangle Proportionality Theorem in real life?
The triangle proportionality theory may be used to calculate the length of diversion roads and the quantity of wood required to build support beams.
This rule will not only assist you in trigonometry, but it will also teach you how to see life more realistically, critically, and even safely.
