The point would be (-4,-9) im pretty sure
180°-100°= 80° (angle 1)
180°-150°= 30° (angle 2)
180°-80°-30°= angle 3
angle 3 = 70°
∴ the interior angles are 80°, 30° and 70°
The expressions 14, 6 + 8, and (6 + 8) are equivalent because they are all equal to 1
<h3>Equivalent expression</h3>
14
6 + 8
= 14
(6 + 8)
= 14
The coefficient of (6 + 8) is 1, so, the expression remains the same.

Answer:
Step-by-step explanation:
sorry I don't give answers to you but I not love you why you are a baby .
I'm going to change all of the hours to 24-hour time to make calculating easier.
7:00 am is still 7:00
9:00 pm is 9+12=21:00
In between 7:00 and 21:00, there are 21-7=14 hours.
Now, since he took off an hour for lunch, we get 14-1=13 hours.
Joe worked for 13 hours.
Good luck!
