Answer: d=70, e=87 and f=23
Step-by-step explanation:
Well we are dealing with opposite angles for d and e, so we could easily find out the answer to those. Once we input our new angles, we have to find f. Because d,e and f are all on a straight line, and all angles on a straight line add up to 180, we can just do
180-87-70=23
So, f=23
Once again,
d=70
e=87
f=23
