Answer:
who mows the lawn for 7 dollars :/
Step-by-step explanation:
He arrives at 9:30 because if you take 8:40 (when dealing with time I like to think of it as a whole number so 8:40 would become 840) then just add 50 minutes to 8:40 (or 840+50 which equals 890 also know as 9:30 because you have to subtract 60 from 90 (because 60 is the limit in time (well technically 59 is)) then add one to 8 like so, which equals 9:30 Enjoy!=)
Answer:

Answer:
x= 45
y= 60
Step-by-step explanation:
For x:
The angles we have are 45 and 90
180°- 45 - 90 = 45
x= 45
For y:
The angles are 30 and 90
180°- 30 - 90 = 60
y= 60
