Question

what is the value of x? x = \boxed{}

Explanation:

Step1: Recall triangle angle sum

The sum of interior angles in a triangle is $180^\circ$.

Step2: Set up the equation

$x + x + 80 = 180$

Step3: Simplify and solve for x

Combine like terms: $2x + 80 = 180$
Subtract 80 from both sides: $2x = 180 - 80 = 100$
Divide by 2: $x = \frac{100}{2} = 50$

Answer:

$50$
