Let us say the first section pipe is AC and CE is the second section of the pipe.

The distance required is the vertical distance of point C from the ground. 

= AC cos 17 + CE cos 37.

= 6.4 cos 17 + 5.2 cos 37

= 6.12 + 4.15

= 10.27 m

Answer: the end of the pipe is 10.27 m below the surface of the ground.
