How To Find Area Of Non Right Angle Triangle Area = 1 2 ca sin b. they are really the same formula, just with the sides and angle changed. example: find the area of this triangle: first of all we must decide what we know. we know angle c = 25º, and sides a = 7 and b = 10. so let's get going: area = (½)ab sin c. put in the values we know: ½ × 7 × 10 × sin (25º) do some calculator. Should be read in conjunction with the 2004 hsc general mathematics examination paper, the marking guidelines and the general mathematics stage 6 syllabus. general comments just over 29 300 candidates attempted the 2004 general mathematics hsc examination paper, slightly fewer than the 2003 number of candidates. Solution. now that you know the equation for the area of a triangle in terms of two of the sides and the included angle, we can use that to solve for the area of the bermuda triangle: a a a a = 1 2ab sin θ = 1 2(950)(975) sin60∘ = 1 2(950)(975)(.866) = 401066.25. the area of the triangle is approximately 401,006 square miles. Non right angled triangles.
