Question

Find the degree measure corresponding to the radian measure -(5π/4)c​

Answer 1

Answer:

With this proportion:

α

d

:

α

r

=

180

°

:

π

in whitch

α

d

is the measure of the angle in degree,

and

α

r

is the measure of the angle in radians.

So, if you want to convert an angle from radians in degree:

a

d

=

α

r

⋅

180

°

π

and if you want to convert an angle from degree to radians:

a

r

=

α

d

⋅

π

180

°

.

In our case:

a

d

=

5

4

π

⋅

180

°

π

=

225
