The answer would be (540 - (111 + 103 + 122 + 90[because of the right angle]) and 540 is the total angle measurement of a pentagon (or a 5 sided figure)
Answer:
16
Step-by-step explanation:
The mean of a group of values is calculated as
mean = 
Given 5 numbers with a mean of 12, then
= 12 ( multiply both sides by 5 )
sum = 60
let the number removed be x , then
= 11 ( multiply both sides by 4 )
60 - x = 44 ( subtract 60 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
The number removed was 16
Between 10 and 11, all the others would be to much or to little
