Question 234996: PLEASE HEPL ME TO SOLVE DOES FUNCTIONS:

PLEASE HEPL ME TO SOLVE DOES FUNCTIONS:
Use a calculator
1.sin 205degree
= -0.422618261
2.cos (-140degree)
= -0.766044443
--------------
3.tan (-40degree)
-0.839099631
------------
4.sin 30degree + tan 45degree times cos 90degree
= 0.5 + 1*0 = 0.5
#4 is ambiguous. Is cos multipled by tan(45)? or by the sum?
Parentheses are free, use some.
