Ответ:
a = 20; b = 10sqrt(3)
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is
1 : sqrt(3) : 2
b = 10 * sqrt(3)
b = 10sqrt(3)
a = 2(10)
a = 20
a = 20; b = 10sqrt(3)
Ответ:
Total = 25 + 45 + 10 = 80 mins = 1 hour 20 minutes.
So we need to subtract this from 9:00 am
9 : 00 - 1: 20 = 7: 40
So he has to leave the house at 7:40 am.
And he shouldn't do any other thing, but to follow the schedule in the question.
Like he shouldn't stop for a chat or snack.
Cheers.
