The triangle ABC is a right triangle
The length of AC is 12.00 cm
<h3>How to determine the length of AC</h3>
From the figure, we have the following parameters:
Length AB = 13 cm
Angle A = 22.6 degrees
Represent the length AC with b.
So, we have the following cosine ratio
Substitute known values
Make b the subject
Evaluate the product
Hence, the length of AC is 12.00 cm
