Technically, age is a vector as time is a dimension. It is in the forward time direction, so I suppose an angle of 0 degrees is appropriate. However, as you can see by the other answers, no one looks at it like that and you should probably answer "scalar."
Temperature is scalar because it is a measure of the energy concentrated in the matter in a volume (three physical dimensions) rather than something formed in a single dimension.

A vector has magnitude AND direction.
Age and temperature DO NOT have direction so both are scalar quantities.

Both have magnitude (size). Neither has direction. They are therefore both scalar.

They are both scalars.
You can't say "10 degrees celcius" in a northerly direction - it makes no sense.
