As all the Angles in the Given Triangle are Equal

⇒ The Given Triangle is an Equilateral Triangle

We know that in an Equilateral Triangle all sides are Equal

Let us Equate any two sides, to find the value of x

⇒ 4x - 30 = 2x + 20

⇒ 4x - 2x = 30 + 20

⇒ 2x = 50

⇒ x = 25

Answer:

⇒ 4x - 30 = 2x + 20

⇒ 4x - 2x = 30 + 20

⇒ 2x = 50

⇒ x = 25
