30/75 = 12/x 30 x=75 12 30x=900/:30 x=30
By using proportion , the value of x is,
⇒ x = 30
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
the **pair **of **polygons **is similar.
Hence, By using proportion we get;
⇒ 30/12 = 75/x
Solve for x by **cross multiply, **
⇒ x = 75 x 12 / 30
⇒ x = 30
Thus, By using proportion , the **value **of x is,
⇒ x = 30
