Area of the Triangles are denoted by the following formulas: 1. Basic Formula, A = ½ * base* height, where base is known and height is perpendicular to the base. 2. 2 sides and an included angle, A= 12 * a * b* sin 4, where a and b are two known sides and is an included angle of the two known sides. 3. Hero's Formula, A = √√s(sa)(s - b)(sc), where S = 1/2 (a+b+c), where a, b and care the three known sides of the triangle. Questions: 1. Solve the area of the triangle. 80'37' Dividing Line- 1690.54 m 1690.54m 80°37 80 37 11'32'

Area of the Triangles are denoted by the following formulas:
1. Basic Formula, A = 12 * base * height, where base is known and height is
perpendicular to the base.
2. 2 sides and an included angle, A = 12 * a * b* sin 4, where a and b are two known
sides and is an included angle of the two known sides.
3. Hero's Formula, A=√√s(s − a)(s - b)(s—c), where S = ½ (a+b+c), where a, b
and c are the three known sides of the triangle.
