Question

A triangle has a perimeter of 13 and one side of

Answer 1

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".

Answer 2

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
