Uhhhh.....    None?  ?  

d = dimes                     value = 10d

q = quarters = 36 -d     value = 25 (36-d)            the values summed = 420

10d      +        25(36-d)     =       420     solve for d =# dimes    then  # q = 36-d

97*2-90 = 104^o

Area of a triangle =   1/2 base * height         base = 6 + h 

        140              =  1/2  (6+h) * h

         280 = h^2 + 6h

           h^2 + 6h - 280 = 0    Quadratic Formula or factoring shows   h = 14      so base = 20

       (h-14)(h+20) = 0      h =   14  or  -20 (throw out)

There are 52! ways to arrange the 52 cards of the deck

   there are only 51 ways to have the ace of hearts directly on top of the king of hearts in the shuffled deck positions

     but that leaves the other 50 cards to arrange in any order or  50!

52!  - 51 * 50!= 52!-51! =

 ( I think !)

....but how do you know the image is drawn to scale????

5 ft * sin 5^o     * 12 in/ft  = ..........inches

10 = a      ( 10 thousand)

10 = 2x^2 - 31x + 25

   0 = 2x^2 -31x + 15     use Quadratic Formula t find x = 15   or  1/2     months  

Sounds lke you have an equilateral triangle.....all the sides are the same size!      There is no 'smaller' and 'bigger' in this triangle .
