Answer:
a) Angle XBC = 55 because XY is parallel with BD
b) As given, XB = XC, so that triangle XBC is the equilateral triangle.
As XBC is equilateral triangle, angle XBC is equal to angle XCB
Angle XBC = 55° => Angle XCB = 55°
In a triangle, the total value of three corners are equal to 180°
So that: Angle XBC + Angle XCB + Angle BXC = 180°
=> 55° + 55° + Angle BXC = 180 °
=> Angle BXC = 70°
225*(x+1/25)+225*(y-4/9)=225*1
9(x+1)+25(y-4)=225
9x+9+25y-100=225
9x-91+25y=225
9x=225+91-25y
9x=316-25y
x=316/9-25/9
If half a gallon of milk is 3 dollars then you should be able to buy one gallon for 6 dollars. Therefore 5 dollars can buy 5/6 gallons of milk.
