Two sides of a triangle have length 3m and 1m. The angle between them is decreasing at the rate of 1/ min . How fast is the length of the third side changing when the angle between the two other sides of fixed length is 30"? (Hint: Convert your angles to radians) G) A) The side length is decreasing at the rate of 11' m/ min 120V10 333 O B] The side length is increasing at a rate of 3 103 mm 0 C} The side length is increasing at a rate of 3 103 mm 0 D) The side length is decreasing at a rate of 3 2(10 Mam! mm
