They show F2 as normal to the 20N force, so it makes a 70 degree angle with the x-axis.
 
More in depth explanation please?

What else would you like to know? The angle between F2 and the 20N force is shown to be 90 degrees.
The 20N force is shown to make an angle of -20 degrees with the x-axis.

90 + (-20) = 70 and this is the angle that F2 makes with the x-axis.

Given this angle just project F2 onto the x and y axes as usual

[MATH]F2 = (F2_x,~F2_y) = |F2| (\cos(70^\circ),~\sin(70^\circ))[/MATH]
