Try this solution (this is not the shortest way):
1. The rule: s=180(n-2), where s - the sum of the internal angles of a polygon, n - the number of the internal angles of the polygon.
2. According to the rule described above, the sum of the internal angles of the given polygon is: s=180*(6-2)=720°;
3. Using the calculated sum it is possible to determine x:
x=720-(90*2+135*3)=135°.
Answer: 135°
Step-by-step explanation:
81
I think this should be the answer
8 . 9 10^(5+3) is the answer (B)
The 8 and 9 are multiplied and you add the exponents when you multiply 10^3 and 10^5.
Each of the eggs is 3.5 and a dozen is 12
So, we multiply 12 by 3.5 to get 42 grams
The dozens of eggs is 42 grams.
Hope this helps!
