You can picture this in your head or you can do the math. You can see that the mast and the string make a right triangle. Now you need to picture a 12 foot tall string attached to the top of the mast and the attached 4 feet away from the bottom. Then all you have to do is see which answer makes the most sense.
25) It is a right triangle
3²+4²=5²
9+16=25
25=25
26) It is a right triangle
6²+8²=10²
36+64=100
100=100
27) Not a right triangle
5²+5²=10²
25+25=100
50=100
28) It is a right triangle
5²+12²=13²
25+144=169
169=169
Hope this helps :)
