40/60 = 2/3 of the teachers are from Ireland.
Answer: 67°.
Step-by-step explanation:
1) m∠PMR=m∠LMN=3x+19°;
2) m∠LMN+m∠LMP=180°, it can be written as 3x+19+9x-31=180;
3) if to solve the equation 3x+19+9x-31=180, then x=16;
4) m∠PMR=3x+19=48+19=67°.
You can find the slope of an equation by looking at what number comes before x. Making the slope being -1/2 because that's the number that comes before x.
