The sum of the interior angles of an $n$ -gon is

$180^\circ(n-2)$

So if the total is 5400 deg, then

$5400^\circ=180^\circ(n-2)\implies n-2=30\implies n=32$

Answer:

7 times during the first 15 minutes

Step-by-step explanation:

Remember that

$1\ min=60\ sec$

$15\ min=15(60)=900\ sec$

Decompose the numbers 18 and 42 in prime factors

we know that

$18=(2)(3^2)$

$42=(2)(3)(7)$

Find the least common multiple (LCM)

The LCM is

$(2)(3^2)(7)=126\ sec$

we need to find all multiples of 126 that are less than or equal 900.

$126*1=126\ sec\\126*2=252\ sec\\126*3=378\ sec\\126*4=504\ sec\\126*5=630\ sec\\126*6=756\ sec\\126*7=882\ sec$

therefore

7 times during the first 15 minutes
