First, let's start by figuring out how much Kendra gets paid per day. To do this, we can divide 300 by 5. 300 / 5 equals $60 per day.
Next, we can take the amount she gets paid per day and multiply it by the number of days, 24. 24 * 60 = $1440.
At the rate of $60 per day, Kendra will get paid $1440 for working 24 days.
Hope this helps!! :)
Answer:
x = 60°
y = 50°
Step-by-step explanation:
✅x = 180° - (50° + 70°) (sum of interior angles of a triangle theorem)
x = 180° - 120°
x = 60°
✅Based on the exterior angle theorem, the sum of the opposite interior angles of a triangle = the exterior angle.
Therefore,
50° + 60° = x + y
Plug in the value of x
50° + 60° = 60° + y
110° = 60° + y
y = 110° - 60°
y = 50°
