WebIn a ABC, let a,b and c denote the lengths of sides opposite to vertices A,B and C respectively. If a=7,b=3,c=5 and ab (tan B 2+tan C 2)(tan A 2+tan C 2) + bc (tan A 2+tan C 2)(tan A 2+tan B 2) + ac (tan B 2+tan C 2)(tan A 2+tan B 2) equals k, then the value of √k+ 1 2 is Q. If θ is the angle between unit vectors → a and → b, then sin(θ 2) equals WebArea (∆ABC) = 1/2 × ab × sin (C) When sides 'a' and 'c' and included angle B is known, the area of the triangle is: Area (∆ABC) = 1/2 × ac × sin (B) Example: In ∆ABC, angle A = 30°, side 'b' = 4 units, side 'c' = 6 units. Area (∆ABC) = 1/2 × bc × sin A = 1/2 × 4 × 6 × sin 30º = 12 × 1/2 (since sin 30º = 1/2) Area = 6 square units.
