We don't need the answers.  Let's do the problems.

In triangle ABC with sides a,b,c labeled in the usual way, the Law of Sines is

[tex]\dfrac{\sin A}{a} = \dfrac{\sin B}{b} = \dfrac{\sin C}{c}[/tex]

Side a is opposite vertex A, etc.

1. A=46, B=29, a=x, b=5

a/sin A = b/sin B

a = b(sin A)/sin B

x = (5) sin 46 / sin 29 = 7.41878636786

Answer: x=7.4

2.  We don't have to spell it all out with a, b and c.

x/sin 65 = 22/sin 53

x = 22 (sin 65)/sin 53 = 24.96604654309146

Answer: x=25.0

3. x/sin 15 = 12/sin 128

x = 12 sin 15/sin 128 = 3.941352991713482

Answer: 3.9

4. x = 18 sin 73 / sin 59 =  20.081827192002002 = 20.1

5. Trickier, we need the missing angle 180-19-26=135

x = 32 sin 19 / sin 135 = 14.73353278 = 14.7

6. 180-78-75=27

x = 28 sin 27 / sin 75 = 13.16015541 = 13.2

7. 180-51-70=59

x = 9 sin 59 / sin 70 = 8.20960549830328 = 8.2

8. 180-52-33=95

x/ sin 33 = 16/sin 95

x = 16 sin 33 / sin 95 = 8.747511482 = 8.7

All the various parts of the question is calculated in the explanation part. This question determined by using law of sines.

We have to find the value of x.

In triangle ABC with sides a,b,c labeled in the usual way, the Law of Sines is

[tex]\bold{\dfrac{SinA}{a} =\dfrac{SinB}{b} =\dfrac{SinC}{c}}[/tex]                                       ..........(1)

(1) Given that:

 A=46, B=29, a=x, b=5,put this values in (1)

[tex]\dfrac{Sin\;46}{x} =\dfrac{Sin\;29}{5} \\\\x=7.418[/tex]

a = 7.418

(2)  Given: A = 65,B = 53, put this value in (1)

      [tex]\dfrac{x}{sin\;65} = \dfrac{22}{sin \; 53}[/tex]

x = 24.96

(3) Given that: A= 15, B = 128, put this value in (1)

[tex]\dfrac{x}{sin\;15} = \dfrac{12}{sin \; 128}[/tex]

x = 3.9

(4),A=73,B=59 put this value in (1)

[tex]x= 18\dfrac{sin\;73}{sin\;59}[/tex]

x = 20.1

(5) Now, find the missing angle 180-19-26=135

[tex]x= 32\dfrac{sin\;19}{sin\;135}[/tex]

x =  14.7

(6) Now, find the missing angle 180-78-75=27

[tex]x= 28\dfrac{sin\;27}{sin\;75}[/tex]

x = 13.2

(7) Now, find the missing angle  180-51-70=59

[tex]x= 9\dfrac{sin\;59}{sin\;70}[/tex]

x =  8.2

(8) Now, find the missing angle 180-52-33=95

[tex]\dfrac{x}{sin\;33} = \dfrac{16}{sin \; 95}[/tex]

x = 8.7
