Answer:

168.3 cm

Step-by-step explanation:

170.6 cm - 2.3 cm = 168.3 cm

Tema [17]

Answer:

See below.

Step-by-step explanation:

The Slope of PQ is (v - z) / (w - x).

The slope of P'Q' =

(v + b) - (z + b)

---------------------   =   (v - z) / (w - x)

(w + a - (x + a)

Both lines have a slope that is (v - z)/ (w - x).

So both lines are parallel.
