For cosФ×sinФ =0, then either cosФ or sin Ф must be zero.
cos 90 = cos 270 = 0
sin 0 = sin 180 = sin 360 = 0.
So, the values that would give you 0 are:
1. cos 90 sin Ф
2. cos 270sin Ф
3. cos Ф sin 0
4. cos Ф sin 180 and
5 cos Ф sin 360.

6(2x-11)+15=21
12x-66+15=21
12x=21-15+66
12x=72
x=72/12
=6
This is the answer and way of solving
Hope this helps
