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.
Vertical Line Test. A test use to determine if a relation is a function. A relation is a function if there are no vertical lines that intersect the graph at more than one point.
In scientific notation, the number would be 9.3 × 10^-11
The C is a 4. Hope this helped!
