Step-by-step explanation:
The length of another side of the triangle will be 5 so option (B) will be correct.
<h3>What is a triangle?</h3>
A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
Let's say the length of the other sides are x
So,
Perimeter = sum of all sides
13 = x + x + 3
2x + 3 = 13
2x = 10
x = 5
Hence "The length of another side of the triangle will be 5 so".
