Answer:
Side N: 20
Equation: 5 × 4 = 20
Step-by-step explanation:
Look at the other sides, and try to find a "pattern". Just by looking at the bottoms of the triangles, I saw 4 on BC and 16 on FG. I know that 4 times 4 equals 16, so that could be and option.
Now look at the left side. AB has a length of 3, and EF has a length of 12. I know that 3 times 4 is 12. Both times, there was an increase of 4 between the sides of the triangles.
Now, let's apply this to the last side. 5 times 4 is 20. So, the last side would be 20 on triangle EFG, and the equation would be 5 × 4 = 20.
