Sin law

19 / sin25  = DE / sin 65

sin 65^o * 19 / sin 25^o   = DE   

People frequently compain about this trivial typo.....you are not the first ....let it go.  Maybe someday it will be fixed.

   I worry more about the language and syntax  skills of people asking questions.....really poor.  Their errors are FAR more egregious than the " I'am  vs I'm"  in the CAPTCHA.

7x+5 = 9x-5

10 = 2x

x = 5      PT = 7x+5   = 40 units

From P to Q    x goes from 5 to 6     from  Q to T will need to go the same amount    6  to  7       x = 7

                       y goes to  3 to -3          distance = -6                                                   -3 -6          y = -9

Need the diagram.....

slope ,m, between 0,0   and  -4, 3        (3-0)/(-4-0) = -3/4

y = -3/4 x +0    or just  y = -3/4 x

A is less than 90 degrees

sin A = 2 cos A

sinA / CosA = 2

tanA = 2 

Arctan (2 ) = A = 63.43 degrees

Each time you draw a card you have a 4/52 chance of an ace  (or 1/13 chance)

(1/13)⁴ =___________

Here is how to find the 'x' coordinate....(you try to find the 'y')

from endpoint x   to midpoint x    is   3   to  11      a distance of 8    add 8 more to the midpoint x to get the other endpoint 11+8 = 19 = x

  Now you try the same for the 'y' coordinate.....
