A. The temperature goes higher-lower-steady/same-lower-same.
B. I do not understand the question
Check the picture below.
the segment LOJ is a diameter, and therefore the arcLCJ made by that diameter will have a central angle of 180°.
that simply means that the arcLC is 180 - 94, or 86°.
the ∡LJC is an inscribed angle that is intercepting the arcLC, and therefore, by the inscribed angle theorem, it'll be half of arcLC.
The answer is 2, hope this helps !
Cotx can also be written as cosx/sinx. So sinx × cosx/sinx = cosx.
