Answer:the answer is 53 900
Step-by-step explanation:
if you you have to add subtract an then divid
Well we know that A+B+C=180
and we know that A=45 and B=90
so together there 135
180-135=45
so C=45
now we also know that a straight line is 180 degrees so 180-45 =135(angle f)
135+15(angle e)=150
180-150=30
so angle d=30
You can use quarts to convert
first do pints to quarts
then do quarts to gallons
