He usually have to takes 10 seconds to get dress.
1. The adverb 'usually' in your sentence indicates routine - therefore you need to use the PRESENT SIMPLE tense. This particular tense needs the -s at the end for HE / SHE/ IT.
That is why we say '
He usually
takes...'
THIS SENTENCE CANNOT BE SAID IN ANY OTHER WAY.
2.
get dressed - You NEED TO put the
-ed after
dress because this is a situation in which the speaker is talking about something that he did / does
himself. In these situations we must use
GET + PAST PARTICIPLE. The past participle ends in
-ed when the verb is REGULAR (like
to dress).
Some other examples are: GET MARRI
ED
GET DIVORC
ED GET WASH
ED
The above are all examples of regular verbs which take the
-ed ending for the past participle.
Some examples of irregular past participles are: GET LOST
GET CAUGHT
GET BROKEN
The above 3 examples DO NOT end in
-ed because they are NOT regular.
