Different species of fish have different requirements for the temperature and ph of the water in which they live. the gold swordtail requires a temperature of 73°f plus or minus 9°f and a ph level of 7.65 plus or minus 0.65.† find the lower and upper limits of the temperature and the ph level of the water in which a gold swordtail lives.
(a) the temperature
lower limit °f
upper limit °f
(b) the ph level
lower limit __
upper limit __

10% of increase is the final answer! : )

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)
