We need to look at 2 similar triangles
1) big one: legs - a,b, and hypotenuse - c
2)small one: legs - h,s, and hypotenuse - b.
Corresponding sides:
hypotenuse - c and hypotenuse - b,
big leg - b and big leg - s,
small leg - a, and small leg h.
?(/b(big leg, big triangle)= b(hypotenuse, small triangle )/s (big leg, small triangle)
? should be hypotenuse of the big triangle, c.
Answer is second one c.
I think the answer might be 280
They repeat by adding that same number again and again
-6.86666666667 this is the answer for your question
Answer:
Find out the what is the eighth term in the arithmetic sequence defined by the explicit formula.
To prove
As given the explicit formula for the arithmetic sequence .
Put n = 8
Therefore the eighth term in the arithmetic sequence is 23 .
