Question

1. solve for x. 4(2x - 4) = 2(x - 5)

(2x - 4)/2 = (x - 5)/4

1. qrs ~ nop. list the pairs of congruent angles. write the extended proportion that relates the corresponding sides for the similar triangles.
2. the pair of polygons shown below is similar. what is the scale factor from δxzy to δabc?
3. are the two triangles similar? how do you know?

Explanation:

Answer:

\(x = 1\)
\(\angle Q \cong \angle N\), \(\angle R \cong \angle O\), \(\angle S \cong \angle P\); \(\frac{QR}{NO}=\frac{RS}{OP}=\frac{QS}{NP}\)
\(\frac{1}{2}\)
Yes, by AA similarity (if two angles of one triangle are congruent to two angles of another triangle, the triangles are similar)
