just put in order greatest to least
1 is 52 2 is 30 3 is 30 4 is 62 5 is 118
It is neccesary because you cannot subtract them without having a common denominator so you have to rename 4 1/2
Answer:
1. 142. 2. adjacent angles.
Step-by-step explanation:
1. because it is less then 180, that would be flat, and it is bigger then 132.
2. because they are adjacent to each other.
Answer:
103°
Step-by-step explanation:
The total angle in a nonagon is 1260. To get the missing angle, we add up all the given angle together and subtract it from 1260.
138 + 154º + 145° + 132° + 148° + 143 + 147 + 150 = 1157
1260 - 1157 = 103
Therefore, the missing angle is 103°
