Sum of inner angles of triangles

Webup of two triangles. The sum of the angles in a triangle is 180°, so 180 (20 30)−+ = x and x =130°. 3. What is the sum of the interior angles in a quadrilateral? The sum of the interior angles in a quadrilateral is 360°. 4. What is the sum of the interior angles in a pentagon? A pentagon is formed from 3 triangles, so 3•=180 540°. 5. Web6 Dec 2015 · 4 Answers Sorted by: 5 You need more parentheses. 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.
