Two fixed sides of a triangle are 15.6 m and 18 m in length and the angle between them is increasing at a rate of 0.09 rad/s. Find the rate at which the area of the triangle is increasing when the angle between the sides of fixed length is 7/3 Note: Write only the numerical value of the rate, the units are already written. Write the exact answer not the decimal approximation (for example write not 0.8) Answer. The area of the triangle is increasing at a rate of G E m2 Is
