Answer:
20
Step-by-step explanation:
100 + 60 = 160
There are 180 degrees in a triangle so we do 180-160 = 20
Answer:
80 degrees
Step-by-step explanation:
In any polygon with number of sides = n, the sum of measures of its internal angles is equal to (n-2)*180
Now, for a nonagon:
number of sides = 9
sum of internal angles = (9-2)*180 = 1260 degrees
We are given the measures of seven of its angles and we know that the other two are equal. Assume that each angle of the remaining two angles has a measurements = x degrees
Therefore:
sum of angles = 138 + <span>154 + 145 + 132 + 128 + 147 + 130 + x + x
1260 = 974 + 2x
2x = 1260 - 974
2x = 286
x = 143 degrees
Based on the above calculations:
The measure of each angle of the remaining two angles is 143 degrees</span>
If you are trying to find the new hourly pay after the 15% decrease, you will multiply the $25 and 0.15 to get 3.75. After that, you would subtract 3.75 from the $25 and you would get $21.25. So the new hourly pay is $21.75.
