rotated after 7 minutes?

In 7 minutes, the clock has rotated 42 degrees

Solution:

Given, A clock is constructed using a regular polygon with 60 sides.  

The polygon rotates every minute.  

As there will be 60 minutes in clock, and this clock has 60 sides, each minute represents a side.  

Now we know that, in a clock, 1 hour = 60 minutes

60 minutes = 360 degrees

Then, 7 minutes = “n” degrees

So, by criss cross multiplication,

Hence, in 7 minutes, the clock has rotated 42 degrees

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
