Ratio of 2 complementary angles = 4:5
Let first angle be 4x
Let second angle be 5x
Sum of two complementary angles = 90
4x + 5x = 90
9x = 90
x = 90/9 = 10
First angle = 4x = 4*10 = 40
Second angle = 5x = 5*10 = 50

Answer:
Johnny and his family left home at 10:00.
Step-by-step explanation:
First, You add all of the minutes up,
45+20+10= 75
Then convert the minutes to hours,
75 mins = 1 hr and 15 mins.
Add the hours together,
1 hr + 2 hrs = 3 hrs
Then add minutes,
3 hrs and 15 minutes
Subtract 3 hrs and 15 mins from 13:15,
13.15 - 3.15 = 10:00
Your answer is:
Johnny and his family left home at 10:00.
