Step-by-step explanation:
[tex](2x + 65) \degree + (3x + 40) \degree = 180 \degree \\ (sum \: of \: internal \: \angle \: s \: between \: two \: \\ \parallel \: sides) \\ \therefore \: 5x + 105 = 180 \\ \therefore \: 5x= 180 - 105 \\ \therefore \: 5x= 75 \\ \therefore \: x= 15 \\ \therefore \:(2x + 65) \degree = (2 \times 15 + 65) \degree = 95 \degree \\ \therefore \:(3x + 40)\degree = 85 \degree[/tex]
