Answer:

Step-by-step explanation:
Given that
is the length measured in meters and
represents the same length measured in centimeters.
Let us first have a look at the relationship between meters and centimeters units of length.
1 unit of length in meters = 100 units of length in centimeters
Therefore, it can be said that:
2 units of length in meters = 200 units of length in centimeters
3 units of length in meters = 300 units of length in centimeters
4 units of length in meters = 400 units of length in centimeters
OR
units of length in meters = 100
units of length in centimeters
It is given that
is the length in centimeters.
Therefore, the <em>proportional equation</em> can be written as:

Answer:
x = 3π/4, 5π/4
Step-by-step explanation:
cos(x+2π) = -√2/2, [0,2π]
cos(x)cos(2π)-sin(x)sin(2π) = -√2/2
cos(x) = -√2/2
x = 3π/4, 5π/4
Remember that the cosine function is periodic, so cos(θ+2π)=cos(θ).
