Which unit of measurement is used in the metric system?

tons
kilograms
miles
gallons

Kilograms

Step-by-step explanation:

Given that there are four measurements for weights as

tons, kilograms, Miles and gallons.

We have to find the one which is used by metric system

We know that metric system uses MKS method for units of measurement namely metre for length, kilogram for weight and seconds for time.

So here kilogram is the right answer.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

the answer is 8/21

hope this
