∠AXY=∠XBC=55°(corresponding angles)

XB=XC⇒ΔXBC is isosceles, so ∠XBC=∠XCB=55°

The sum of all the angles in a triangle is 180°⇒

55°+55°+∠BXC=180°

∠BXC=70°

devlian [24]

Answer:

B. 3 square feet

Step-by-step explanation:

The formula for surface area is:

2lw+2lh+2wh

Box F's surface area is just plugging in those variables

2(3)(3)+2(3)(3)+2(3)(3)=54

Box J's surface area is the same way

2(2)(4.5)+2(2)(3)+2(4.5)(3)=57

The difference is 57-54=3

The answer is B. 3 square ft
