Answer: y = 80*
all circles have 360* so we can subtract what we have to get what we want
360 - 110 - 90 - 80 = 80*
-1.6 is your answer :))))
Answer:
false
Step-by-step explanation: they do not have the same degree
45x=25+55+x
25+55=80
45x=80+x
subtract x from both sides
44x=80
divide by 44
80/44=20/11 or 1.82
x=20/11 (or 1.82)
