Answer:
s=5
Step-by-step explanation:
As you can see, you have a whole block that is 20. Then you have another block that is broken down to 4 squares.
So....
4s=20
divide 4 to 4s
divide 4 by 20
so s=5
For two triangles to be congruent, we need to show is two of the
1. corresponding angles are congruent,
or,
2. all three pairs of corresponding sides are proportional,
or
3. two pairs of corresponding sides are proportional AND the included angles are congruent.
Choice D saus, angles Q and Q' are congruent, angles R and R' are congruent, therefore satisfies the first criterion that at least two corresponding angles are congruent.
A. AC because of how it is directly across from the Angle
