Calculate how many liters you need to be half full:
50 liters x 50% = 50 x 0.5 = 25 liters to be half filled.
Calculate how many liters are in the tank now:
50 x 0.30 = 15 liters
Now subtract to find how many more liters are needed:
25 - 15 = 10 more liters.
Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, thus
sum = 180° × 3 = 540°
