The geometric mean of two numbers is the square root of their product:

So, if the product is 8, the geometric mean is 
The coefficient for y is -5 in the first equation, +2 in the second equation, so the least common multiple is -10
The answer is C. Greenwich,England.
Answer:
54
Step-by-step explanation:
The two angles add to 90 degrees since they are complementary
the ratio is 3:2
Multiply by x
3x:2x
Add them together and set equal to 90
3x+2x=90
5x=90
Divide each side by 5
5x/5 = 90/5
x = 18
The first angle is 3*18 = 54
The second angle is 2*18 = 36
