What is the measure of angle R?

Step-by-step explanation:

∠R + ∠S + ∠T = 180 {Angle sum property of triangle}

∠R + 56 + 30  = 180

         ∠R + 86 = 180

               ∠R   = 180 - 86

                ∠R =   94

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
