You have: A = (180/pi)*asin (a/2*R); You need: A = (180/pi)*asin (a/ (2*R)); What you wrote is equivalent to: A = (180 / pi) * asin ( (R * a) / 2); You should also check your inputs so that a 'triangle' with sides 1, 1, 3 is rejected, for example. WebTo solve the triangle we need to find side a and angles B and C. Use The Law of Cosines to find side a first: a 2 = b 2 + c 2 − 2bc cosA a 2 = 5 2 + 7 2 − 2 × 5 × 7 × cos (49°) a 2 = 25 + 49 − 70 × cos (49°) a 2 = 74 − 70 × 0.6560... a 2 = 74 − 45.924... = 28.075... a = √28.075... a = 5.298... a = 5.30 to 2 decimal places
