Answer:
Step-by-step explanation:
By geometric mean theorem,
In a triangle ABC,


y² = 60
y = √60
y = 7.75
Similarly, 

x² = 40
x = √40
x = 6.32
I don't know if that's your whole question, but I'm going to say 153,729,991.
One hundred fifty three million, seven hundred twenty nine thousand, nine hundred ninety one.
Im pretty sure the answer is 65
