1. Answer:

   (B) 5

   Step-by-step explanation:

   A triangle has a perimeter of 13 and one side of

   length 3. If the lengths of the other two sides are

   equal, what is the length of each of them?

   (A) 4

   (B) 5

   (C) 6

   (D) 7

   (E) 8

   having two equal sides is isosceles, remove the known angle from the perimeter and divide by two

   (13 – 3) : 2 =

   10 : 2 = 5

   ——————–

   check

   5 + 5 + 3 = 13

   the answer is good

2. The length of another side of the triangle will be 5 so option (B) will be correct.

   What is a triangle?

   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”.
