Guest is correct....I did not quite read the question corectly.....

   Largest exterior angle would have the smallest interior angle

     largest exterior angle is  7 x 24 = 168 degrees

        Interior + exterior = 180 degrees             180 - 168 = 12 degrees for the smallest INTERIOR angle !     THANX < guest !

All of the exterior angles sum to 360 

360 / ( 3+ 5 + 7) = 24

   the exterior angles are then   3 * 24           5 * 24        and     7 * 24

    24 * 3 = 72 degrees would be the smallest

At 10:00 the hour hand is at 300 degrees   .....  it moves 1/2 degree per minute

    so the angle it forms with the 12 : oo position is

       360 - 300 - 1/2 x

     the minute hand moves 6 degrees per minute

     the angle it forms with 12:00   is      6 x

summed they = 90 degrees

360-300-1/2 x     +     6x     = 90

60 + 5.5 x = 90

5.5x  = 30

x = 5.45 minutes   ( 5 min 27 sec)                       so at   10:05:27   the hands form a 90 degree angle

the sugar number is 4        you are using   8    so eerything is doubled   to   2:12: 8      which sums to 22 cups total

tan (angle ) = opposite / adjacent         opposite is 120 ft    adjacent = 1500 ft

   then arctan (angle ) =  120/1500 = _______________  degrees

(k-9)    = a+b        and     a*b = 25           factors of 25 :        5  5      25  1      -5   -5        -25   -1        (these are   'a' and 'b')

                                                                          since we want a square of a binomial.....only the RED pairs above apply ....

Taking each one :

k-9  = 5+5

k = 19                                  binomial is   (x+5)^2   = x^2 + 10x + 25

Can you do the other?                      

Just add the 'like' terms of   f and g together:

(7x^2 + 2x^2)   + ( -5x +4x)   +  (3-6)        for your result.....
