Solve with working much appreciated

Length n = 5 cm

Step-by-step explanation:

Given:

Each angle measure is of 60° for the triangle given in the figure.

Equilateral Triangle:

If all the angles measure of the triangle is 60° then the triangle is said to be an Equilateral Triangle.

Another property of an Equilateral Triangle is

All the Three sides of an equilateral triangles are equal.

Here,

measure of each angle is 60° { Given}

length of one side = 5 cm       {Given}

∴  Length n = 5 cm

answer: add the !

step-by-step explanation: then we will answer
