I can’t see the image you mentioned. Please upload it (or type the three side lengths or the two sides and included angle shown) and I’ll compute angle A.
Meanwhile, here’s how you (or I) will find angle A once I have the numbers:
1. If you have the three side lengths a, b, c (with a opposite vertex A), use the Law of Cosines:
A = arccos((b^2 + c^2 − a^2) / (2bc))
2. If you have two sides and the included angle, use the Law of Cosines to find the third side or use the Law of Sines as appropriate.
3. Use your calculator in degree mode and round the result to the nearest whole degree.
Give me the image or the side measurements and I’ll pick the correct choice (62°, 25°, 28°, or 100°) and show the work.
