Henry is filling up his fish tank with water at a constant rate. At 2 minutes the water level is 16 cm. At 8 minutes the water level is at 34 cm.

Explain how you figured out the water level at 0 minutes.

It would have started to be filled at 10 cm

Step-by-step explanation:

FInd teh difference between 8 and 2 which is 6

Find the difference between 34 and 16 which is 18

Divide 18 by 6 which is 3

Subtract 2(3) = 6 by 16 which is 10

50

Step-by-step explanation:

AE= 40

90° degree angle

90+40= 130

half circle so 180

180-130=50
