The angle at vertex A
is approximately
B
20
C
A
25

Answer 1

To find the angle at vertex A using the inverse tangent (also known as arctan), you'll need the lengths of the opposite and adjacent sides of the triangle at vertex A. Assuming you have these lengths, you can use the formula:

\[
A \approx \tan^{-1}\left(\frac{\text{opposite}}{\text{adjacent}}\right)
\]

Please provide the lengths of the opposite and adjacent sides for vertex A, and I can help you calculate the angle to the nearest whole degree.
