Triangles ABC and DEF are similar, which means corresponding sides occur in ratios with one another. Mathematically, this means
Also, corresponding angles are congruent. These are A and D, B and E, C and F.
As an example, for 21, the above equation turns into
and you can solve for and directly:
The others are solved exactly the same way. In each case, you happen to be given all the side lengths for one of the triangles, and one of the side lengths for the other triangle. So all you need to do is plug in what you know and solve for the remaining two sides.
Remember
so find numbers that add to 5
0+5
2+2+1
1+4
so we can write
those are 3 ways to express
as a product of powers
