25*

Step-by-step explanation:

all angles in a triangle will equal 180*

180-135=45

the two anlges with x need to = 45 \

the number thst works for that is 5          4times5=20 and 5times5=25 togather they = 45  

so "x" equals 5   therefore making <a 25*

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
