Base case: For 
, the left side is 2 and the right is 
, so the base case holds.
Induction hypothesis: Assume the statement is true for 
, that is
We want to show that this implies truth for 
, that
The first 
terms on the left reduce according to the assumption above, and we can simplify the 
-th term a bit:
so the statement is true for all 
.
Answer:
Step-by-step explanation:
triangle value- 180 degrees
since the two bottom angles are alike
62+62= 124
180-124=54
<span>7.158 x 10^9 rounds to 7 x 10^9
</span>7 x 10^9 means 7 followed by 9 zeros.
7.158 * 10^9 is approximately equal to 7 * 10^9 = 7,000,000,000
