Question

A 12cm long wire is bent to form a triangle with one angle 60 , find the sides pf the triangle if area is maximum

Answer 1

Answer:

if one angle is 60 degree than at maximum another angle could only be 90 degree so third angle be 30 degree . so in this type of triangle the ration of side is 3:6:9 both for sides and angles . so following sides that are formed 3cm,6cm and 9 cm

so , area of a triangle is half × base × height i.e

1/2×6×9 = 27 cm square I.e. the most possible area .
