The answer is 77 multiply and add them
The minute hand has swept through 46 minutes on the clock. You have to set up a ratio to solve this:

You can compare the 60 minutes on a clock to 360 degrees because 60 minutes on a clock is one whole rotation. So then, you cross multiply and simplify:

Therefore, the minute hand has swept through an angle with a measure of 276 degrees.
6/(x-8)=2/(x+6)
times both sides by (x-8)(x+6)
6(x+6)=2(x-8)
distribute
6x+36=2x-16
minus 2x both sides
4x+36=-16
miinus 36 both sides
4x=-52
divide both sides by 4
x=-13
