3) Isosceles triangles were used as the main geometric gure in the patches used to make a tent. The equal sides of these isosceles triangles were made to have a constant length of 6.7 ft. Varying sizes of the tent would mean a varying number of isosceles triangles needed. If the angle between the equal sides of the isosceles triangle increases at the rate of 8 rad/sec, determine the rate at which the area of the triangle is increasing when the angle is 75. Enclose in boxes the function generated from this problem together with its derivative. These should be included in the summary of answers
