Answer 1

12.2 cm

Explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, equilateral and isosceles triangle. We say that two triangles are similar if the ratio of their corresponding sides are equal and their corresponding angles are also equal.

Since both triangles are similar, then the ratio of their corresponding sides are equal. Hence:

`(x)/(18) =(17)/(25) \\\\x=(17)/(25) *18\\\\x=12.2\ cm`
