Suppose a roast should be cooked for 45 minutes plus 10 more minutes for every pound the roast weighs. if a roast is properly cooked in 3 hours, how much did it weigh?

1010: 3030

is it i think

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
