Answer:

Yes,  in its atmosphere(21% oxygen) humans can walk on this planet without the aid of a space suit

Explanation:

The atmosphere of the earth has a percentage of 20.946% similar to the planet x with 21% oxygen.

Most living forms depend on the air: oxygen is necessary for the breathing of human beings. In the first 100Km the oxygen composition in the atmosphere remains stable.

Humans are very sensitive to oxygen levels, the magnitude of the oxygen deficit can lead to death but 215 is a  bearable percentage.
