Question

Find the value of X.

Answer 1

All 3 sides of the triangle are the same, which means all 3 inside angles are the same. Each inside angle is 60 degrees.

We now have 3x = 60

Divide both sides by 3:

x = 60/3

x = 20

Answer 2

Answer:

As in the given figure, all the sides are equal i.e., 5 units

It is a equilateral triangle.

In equilateral triangle all the angles are 60°.

$3x = 60 \\ x = \frac{60}{3} \\ \boxed{x = 20}$

20 is the right answer.
