Answer:

$\huge\red{\boxed{\bold{Answer}}}$

➡ By exterior Angle theorem

➡The exterior angle is equal to the sum of two interior opposite angle ...

$60 + 60 = 4x - 80 \\ \\ 120 = 4x - 80 \\ \\ - 4x = - 80 - 120 \\ \\ - 4x = - 200 \\ \\ x = 50$

Hope it helps ✨❤

Answer 2

Step-by-step explanation:

We know that the sum of interior angles of a triangle is equal to the opposite exterior angle.

So,

• 60 + 60 = 4x - 80
• 120 = 4x - 80
• 120 + 80 = 4x
• 200 = 4x
• 200 ÷ 4 = x
• 50 = x
