Let's Evaluate A. Answer the following questions. Show the solution. 1) What kind of triangle whose lengths of the sides are 11, 15, and 9? 2) A triangle has sides 21 and 17. If the remaining side is the longest side, what is the smallest integer value it can take that would still keep the triangle acute? 3) If the lengths of the sides of APQR are 11 cm, 14 cm and 8 cm, then what kind of triangle is APQR? 4) A tower casts a shadow of 16m at the same time that a 2.5m post cast a shadow of 4m. How high is the tower? 5) A sagging door 4 meters by 5 meters is to be made rigid by the addition of a diagonal piece of iron bar. How long must the bar be? 6) A baseball diamond is a square 27m on a side. How far is it from second base to the home plate? 7) A tall building casts a 12-m shadow at the same time a 7-m light pole casts a 3-m sahadow.
