I don't know how to make the delta on the computer either. I usually write as you did. I note that some students use DH for delta H, DT for delta T, DS for delta S, etc.
You answer of 1840 Joules is correct. Good work.
if the specifc heat of iron = 0.46J/g C,how much heat is needed to warm 50g of iron from 20C to 100C
-- I do not know how to make the celcius o above the temperature number
my anwswer
Q = Mx(delta)TxC
Q=50gx80Cx0.46J/gC
Q = 1840 Joules
Delta = the triangle I do not know how to make that on the computer

A couple of points I missed. I CAN make the degree sign as 20o C. But it's a lot easier to just write it as 20o C and almost everyone knows what that means. The other point is to please not the correct spelling of Celsius.
