I think it is 33, according to the scale. 1:33 means one cubic inch of the model represents 33 cubic inches of the actual tractor. Agree?
Use tan because you are dealing with the opposite and adjacent sides
Just write 5-8i and then replace the - sign with the + sign: 5+8i.
Wouldn't r = -10?
because you'd multiply -7 by 3, to get rid of the division.
then you'd add 11.
