Use the triangle shown on the right to answer the question. According to the law on sines, which of the following statement(s) a
Lelechka [254]

Answer:

See below.

Step-by-step explanation:

The law of sines is usually written as a / sin A = b / sin b == c / sin C    where a is the side opposite angle A ,etc.

The first equation is true because it is obtained by cross multiplying

a / sin A = b / sin B,  therefore   b sin A = a sin B.

The second one is not true.

The third and fourth are both true.

Answer:

  WX = 33

  (x, y) = (2, 10)

Step-by-step explanation:

The hash marks tell you WX is a midline, so has the measure of the average of the two bases.

  WX = (PQ +SR)/2 = (27 +39)/2 = 66/2

  WX = 33

__

The hash marks also tell you ...

  PW = WS

  y +4x = 18 . . . . . . substitute the given expressions

and also

  QX = XR

  2y +x = 22 . . . . . substitute the given expressions

__

If you solve the first equation for y, you get ...

  y = 18 -4x

Substituting that into the second equation gives ...

  2(18-4x) +x = 22

  36 -7x = 22 . . . . . . . simplify

  14 = 7x . . . . . . . . . . . add 7x-22 to both sides

  2 = x . . . . . . . . . . . . divide by 7

  y = 18 -4(2) = 10 . . . find y using the above relation

The values of x and y are 2 and 10, respectively.

__

My favorite "quick and dirty" way to solve a set of linear equations is using a graphing calculator. It works well for integer solutions.
