Question

what is the value of x?
x =
triangle with angles 80°, x°, x°

Explanation:

Step1: Recall triangle angle sum

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

Step2: Set up the equation

We have two angles of $x^\circ$ and one angle of $80^\circ$. So, $x + x + 80 = 180$.

Step3: Simplify and solve

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
