Eand f are vertical angles with m e=8x+8 and m f=2x+38. what is the value of x

8x+8 = 2x+38

8x-2x = 38-8

6x = 30

x = 5

So, Your Final Answer would be 5

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
