Answer: A) 3
Explanation:
Since QS bisects ∠PQR, it is given that ∠PQS and ∠SQR are congruent. We can use this to create an equation to solve for x.
Given:
5x° - 8° = 2x° + 1°
Add 8 to both sides of the equation:
5x° = 2x° + 9°
Subtract 2x from both sides of the equation:
3x° = 9°
Divide both sides of the equation by 3:
x = 3
