Answer:
- September
Step-by-step explanation:
The temperature in Beijing, in m months after January, is given by the following equation:

In which m is the number of months after January.
During which month in the year would the temperature reach 55°F?
We have to find m for which: T(m) = 55. So




Now, we apply the inverse cosine, on both sides of the equation, to find the value of m.

Now, with the help of a calculator, in radians:





8.27 months after January, since 8.27 + 1 = 9.28, it happens during the month of September.
By similar triangles ( triangles AFE and ADB are similar)
BD = 1/2 * FE so BD = 11.75 answer
Maybe it’s 2? Let me know if I’m wrong
