Answer:

The angle A for the first question is equal to 43.6 degrees

Step-by-step explanation:

1st step:

[tex]\frac{sin\theta}{20} \times \frac{sin 90}{29}[/tex]

2nd step:

Take 20 to the other side.

[tex]sin \theta = \frac{20(sin90)}{29}[/tex]

3rd step:

Solve the right side and then take the inverse sin of the right side to get the value of theta and you get 43.6 degrees

[tex]\theta = 43.6[/tex]
