In right triangle DEF, we have angle D = 25 degrees, angle E = 90 degrees, and EF = 29.  Find DE to the nearest tenth.  You may use a calculator for this problem.

D = 25

 

 

E = 90           29                   F =  65

 

tan F =   DE / EF

tan (65°)  =    DE  /  29

29 * tan (65°)  =  DE  ≈   62.2
