Answer:

[tex]AC= 32[/tex]

Explanation:

Given

[tex]AB = 29[/tex]

[tex]\angle A = 25[/tex]

Required

Find AC

I will answer the question with the attached triangle

From the attachment:

[tex]\cos A = \frac{AB}{AC}[/tex]

Make AC the subject

[tex]AC= \frac{AB}{\cos A }[/tex]

This gives:

[tex]AC= \frac{29}{\cos (25)}[/tex]

[tex]AC= \frac{29}{0.9063}[/tex]

[tex]AC= 32[/tex]
