Sec2.7: Problem 12 Previous Problem Problem List Next Problem (1 point) Book Problem 30 Two sides of a triangle have lengths 7 m and 14 m. The angle between them is increasing at a rate of 0.03radians /min. How fast is the length of the third side increasing when the angle between the sides of fixed length is 7 /3 radians. Note: The length of the side c of a triangle is given by the law of cosines: c2 = a2 + b2 - 2ab cos(0), where a and b are the other two sides and 0 is the angle between them.
