Please help does anyone know the answer to this?

M = 95°

N = 67°

Step-by-step explanation:

180 - 162 = 18°

6y + 5 + 4y + 7 + 18 = 180

10y + 30 = 180

10y = 150

y = 15

M: 6(15) + 5 = 95°

N: 4(15) + 7 = 67°

Verification: 95 + 67 + 18 = 180° (correct)

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
