   In ΔJKL, the measure of ∠L=90°, JK = 99 feet, and KL = 58 feet. Find the measure of ∠J to the nearest degree.     

 

   Draw it.  From angle J, you have opposite (58) and hypotenuse (99)      

 

   sin(J)  =  58 / 99     

   sin(J)  =  0.585858 • • •     

          J  =  sin^–1(0.585858 • • •)     

          J  =  35.86^o  rounds  to 36^o
