Given:
The logarithmic expression is:
![\log_718](https://tex.z-dn.net/?f=%5Clog_718)
To find:
The equivalent expression of given expression by using change-of-base formula.
Solution:
The change-of-base formula is:
![\log_ba=\dfrac{\log_ca}{\log_cb}](https://tex.z-dn.net/?f=%5Clog_ba%3D%5Cdfrac%7B%5Clog_ca%7D%7B%5Clog_cb%7D)
The given expression is:
![\log_718](https://tex.z-dn.net/?f=%5Clog_718)
Using the change-of-base formula, we get
![\log_718=\dfrac{\log_c18}{\log_c7}](https://tex.z-dn.net/?f=%5Clog_718%3D%5Cdfrac%7B%5Clog_c18%7D%7B%5Clog_c7%7D)
Where, is a constant and c>0.
Let
, then
![\log_718=\dfrac{\log_{10}18}{\log_{10}7}](https://tex.z-dn.net/?f=%5Clog_718%3D%5Cdfrac%7B%5Clog_%7B10%7D18%7D%7B%5Clog_%7B10%7D7%7D)
Therefore, the correct option is a.
Answer:
The angle of the last point would also be 35 because both sides are congruent. I don't know what else you are asking.
