For given question, x = 4
What is an equilateral triangle?
"It is a triangle with all three sides of equal length and each angle measures 60°."
What is an equation?
"It is a statement which consists of equal symbol between two mathematical expressions."
From given figure,
we can observe that the all sides of the triangle are equal.
This means, the given triangle is an equilateral triangle.
So, each angle of triangle measures 60°.
So, we get an equation,
⇒ 17x - 8 = 60°
⇒ 17x = 60 + 8
⇒ 17x = 68
⇒ x = 68/17
⇒ x = 4
