Answer:
2.5 ft
Step-by-step explanation:
As radius is perpendicular to tangent ,
LT KT
By pythagoras theorem:
LT² = LK² - KT²
LT² = (6.5)² - 6²
LT² = 42.25 - 36
LT² = 6.25
LT = 2.5 ft
LT = radius = 2.5 ft
23.8/28=0.85
They used 0.85 liters of water Each day.
Hope this helps
Pretty sure is 63 degrees since the one next to it is exactly the same and its 63 degrees
First one is c
second one is b
and third one is c
