Atriangle has two constant sides of length 5 feet and 7 feet. the angle between these two sides is increasing at a rate of 0.9 radians per second. find the rate at which the area of the triangle is changing when the angle between the two sides is .

Step-by-step explanation:

Given

Two sides of triangle of sides 5 ft and 7 ft

and angle between them is increasing at a rate of 0.9 radians per second

let is the angle between them thus

Area of triangle when two sides and angle between them is given

Differentiate w.r.t time
