Answer:
110°
Step-by-step explanation:
All the angles add to 360.
Y+W = 180
and V+X = 180
to find W,
W = 180 - Y
W = 180-70
= 110
Step-by-step explanation:
The easiest approach is to realise that one hour is 3 times longer than
20
minutes. The longer the time, the more they will pave.

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by
20
) and them multiply by
60
to find how much in one hour.
