I guess you are talking about a triangle . The 3 angles add up to 180 degrees.
b + c = 180 - 25 = 155 degrees
When b > 51 degrees then
c <= 155 - 52
c <= 103 degrees
When b < 57
c >= 155 - 56
c >= 99 degrees
Possible measurements for angle c :=
99 =< c <= 103 (answer).
You are just taking plus and minus numbers.
You start at 62.3
You go up 13.9
Then you go down - 21.5
End temperature = 62.3 + 13.9 - 21.5
Edm temperature = 54.7 <<<<< answer
Answer:
A. 5a+10
Step-by-step explanation:
a + 20 + 4a - 10
= a + 4a + 20 - 10
= 5a + 10
Answer:
20.9-26.2 = -5.3 to the left (or 5.3 to the right)
