How find an angle of right triangle if you have the lengths of 2 sides?
Step 1: Begin by using the cosine rule to find the unknown side. a² = b² + c² - 2bc cosA. Taking the positive square root. Use the sine rule to find the smaller of the two unknown angles. a/sin A = b/sin B. Find the inverse sin of the answer more?
