<h3>Answer:</h3>

a) no solutions

b) B = 49.8° or 130.2°

<h3>Explanation:</h3>

a) By the law of sines, ...

... sin(B)/b = sin(A)/a

... sin(B) = b·sin(A)/a = (11/9)·sin(61°) = 1.069 . . . . . not realizable

there is no solution

b) As before, ...

... sin(B) = (28/25)·sin(43°) ≈ 0.763838...

... B = arcsin(0.763838...) ≈ 49.80°

The side length b is longer than the side length a, so there will be two solutions. The other angle for B is the supplement to this one:

... B = 180° -49.8° = 130.2°

(4/x - z/y=0) <br> (10/x+z/y=0)
galina1969 [7]

Answer:

Some of the other answers are good examples of solving a system of three equations in three unknowns, which is what this problem is asking. Though the simplest way to solve this problem is actually to notice that, if we sum the three equations, we get:

 

   X + Y = 10

   X + Z = 20

+  Y + Z = 24

----------------

2X + 2Y + 2Z = 54

 

Factoring out the 2, we have 2(X + Y + Z) = 54, and dividing both sides by 2 reveals that X + Y + Z = 27.

Step-by-step explanation:

hopefully this helps
