I need this fast guys. and please show step by step process

x°=48°

Step-by-step explanation:

angle Y=x°

angle Z= angle y, because equal side of the angles are equal.

so, angle X +angleY+ angle Z=180° ( angle sum property of triangles)

therefore 84°+x°+x°=180°

2x°=180° -84°

2x°=96°

x°=48°

12.5 feet

step-by-step explanation:

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
