Answer:
60
Step-by-step explanation:
[tex]3x + 55 = 85 \: (angles \: in \: linear \: pair) \\ \\ \implies \: 3x = 85 - 55 \\ \\ \implies \: 3x = 30\\ \\ \implies \: x = \frac{30}{3} \\ \\ \implies \: x = 10 \\ \\ \\ 2y - 5 = 95 \: (angles \: in \: linear \: pair) \\ \\ \implies \: 2y = 95 + 5\\ \\ \implies \: 2y = 100\\ \\ \implies \: y = \frac{100}{2} \\ \\ \implies \: y = 50 \\ \\ \\ x + y = 10 + 50 \\ \\ \huge \red{ \implies \: x + y = 60 }[/tex]
