3 sqrt 5 * cos (-pi/8) = x=.......

3 sqrt 5 * sin (-pi/8) = y = .....

Divide the difference of the two intercepted arcs by two to find x

180 - 148    would be the SUM of the two arcs  = 32

Lets call them  L  and R

L+ R = 32

(L-R)/2 = 12     or   L-R = 24    add to the top equation

2L = 56

L = 28

Then   R  (or x in this diagram) = 4   degrees

(e/10^11.8)       is this part written correctly?       is it supposed to be   e^{-10^11.8}       or  what?

I DID write it in detail.....You should be able to do this

= 4/3  pi  2³ =   33.51  mm³

^{divide by 8   to get volume of smaller droplets = 4.189 mm^3}

4.189   = 4/3 pi r³

^{1 = r^3}          now  find r ....haha

(2 1/4 )/4 = 9/4  / 4  =   9/16  each

volume of sphere =  4/3 pi r³

find the original volume   = 4/3  pi  2³  =........

then divide that volume by 8     to find the volume of the smaller spheres   v_1/8

then use the formula again      v_1/8 =  4/3 pi r³      and solve for the  new r of the smaller droplets

7 out of  (7+12 +6)    = (c)Rap music    7 / 25

7/25  x 1250 = ........

[(1.585 x 10-5 x 9.81) + (1.585 x 10-3 x 2.61) + (3.162 x 10-3 x 1.8)] / 14.222 = 0.0731261425959781

just pasted it into web2 calculator......

This is a straightforward Pythagorean Theorem problem....

  the car distances are each of the legs of a right triangle  .... one is 15 km...and the hypotenuse is 17 km... find the other leg

c^2 = a^2 + b^2          c = 17   a =15     find  b

The opening bracket  '  [ '   is missing the closing bracket  '  ]  '
