Answer 2

Answer: First option

Explanation:

By definition, you know that:

`55\°=(170\°-x)/(2)`

Therefore, to calculate the measure of the missing angle, you must solve for x, as you can see below:

- Multiply both sides of the equation by 2.

- Subtract 170 from both sides of the equation.

- Multiply both sides of the equation by -1

Therefore:

`55\°=(170\°-x)/(2)\\\\(2)55\°=(170\°-x)/(2)(2)\\\\110\°=170\°-x\\110\°-170\°=170\°-x-170\°\\(-1)-60\°=-x(-1)\\x=60\°`
