Answer:
x=5
Step-by-step explanation:
The angles of a trangle have to add up to 180 degrees. With that information, we can create an equation:
27+98+(10x+5)=180
125+10x+5=180
130+10x=180
-130 -130
______________
10x=50
/10 /10
x=5
1 + 3 + 5 + 7 + ... + 997
1, 3, 7, ... , 997 are terms of an arithmetic sequence

Answer: 1 + 3 + 5 + 7 + ... + 997 = 249,001.
Powers distribute over multiplications:

So, you have

Now,
is simply 9.
As for
, we have to use the rule

to get

So, the final answer is
