Step-by-step explanation:
1 septillion = 10^6 nonillion
the taking time = 5× 10^-6 / 257.21
= 500× 10^-8 /257.21
= 1.94 × 10^-8 seconds
Answer:
In ∆ABD and ∆ACD
<BAD =<CAD ( each are half of <A )
<D=<D ( each equal to 90°)
AD = AD ( common)
So ∆ ABD is congruent to ∆ ACD.
Then AB =AC (by C.P.C.T)
Hence,∆ABC is an iso - sceles triangle.
No, the question is stating the product of a number (the variable n represents the number) and 10 is 142. In other words, 10 times another number is 142. Hence, the answer would be A.
