Answer: 4.8
Step-by-step explanation:
Corresponding sides of similar figures are proportional, so
![\frac{x}[4}=\frac{6}[5}\\\\x=4\left(\frac{6}{5} \right)=\boxed{4.8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%5B4%7D%3D%5Cfrac%7B6%7D%5B5%7D%5C%5C%5C%5Cx%3D4%5Cleft%28%5Cfrac%7B6%7D%7B5%7D%20%5Cright%29%3D%5Cboxed%7B4.8%7D)
Cos(40)= 21/ (hypotenuse)
hypotenuse(cos(40))= 21
hypotenuse = 21/ cos(40)
21/ cos40 = 27.41
