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°
Answer:
$215.16
Step-by-step explanation:
Assuming he worked:
Tuesday - 4.14 hours
Wednesday - 3.14
Thursday - 7.14
Friday - 5.14
Add all the hours together: 4.14+3.14+7.14+5.14 = 19.56. Now times the hour by his rate of $11.
19.56(11) = $215.16
Answer:

Step-by-step explanation:
3.242424.....
This number can be written as 3 + 0.242424....
We convert the decimal part into fraction
Let x= 0.242424......
Multiply both sides by 100
100x = 24.2424....
x= 0.2424.....
------------------------------------- (subtract it)
99x = 24
Divide both sides by 99
So x= 24/ 99
simplify the fraction

3.242424... can be written as 3 + 0.242424....
Replace the fraction for decimal
So final answer is 
Calculator --- $24
Pen --- 24/3 = $8
Money spent --- 24+8 = 32
Total money --- 32 divided by 2 times 3 = $48
Money left --- 48-32 = $16
