Answer : The value of 'x' is, 25

Step-by-step explanation :

The given triangle is an equilateral triangle in which all angle and sides are equal.

That means,

All angles are 60°.

All sides, AB = BC = AC

Given:

Side AB = 3x - 5

Side BC = 2x + 20

Side AC = 4x - 30

As, AB = BC = AC

So, 3x - 5 = 2x + 20 = 4x - 30

3x - 5 = 2x + 20

3x - 2x = 20 + 5

x = 25

Therefore, the value of 'x' is, 25

the first one, all those points on the line just make a strait line.
