Length of two sides of a triangle are 20 cm and 16 cm and the angle between them is 135^@ :-Find the perpendicular distance of the vertices to the side of length 20cm.

The lengths of two sides of a triangle are 8 cm and 10 cm and the angle between them is 40^circ . Calculate its area. What is the area of the triangle with sides of the same Iength, but angle between them 140^circ ?

The sides of a parallelogram are 8 cm and 12 cm and the angle between them is 50^circ . Calculate its area.

Two sides of a triangle are 8 m and 5 m in length. The angle between them is increasing at the rate 0.08 rad/s. When the angle between the sides of fixed length is (pi)/(3) , the rate at which the area of the triangle is increasing, is a) 0.4 m^(2)//s b) 0.8 m^(2)//s c) 0.6 m^(2)//s d) 0.04 m^(2)//s
