Write the measure in degrees (pi)/4

Answers

Let's see

[tex]\\ \rm\longmapsto \pi/4[/tex]

[tex]\\ \rm\longmapsto \dfrac{\pi}{4}\times \dfrac{180}{\pi}[/tex]

[tex]\\ \rm\longmapsto \dfrac{180}{4}[/tex]

[tex]\\ \rm\longmapsto 45°[/tex]

The solution is: the measure in degrees (pi)/4 is 45°.

Here, we have,

given that,

we have to find  the measure in degrees (pi)/4.

now, we know that,

Measure of an Angle in Degrees = 180°        

Measure of an Angle in Radians is:

180° × (π/180°) = π = 3.14 Rad

so, we have,

π/4

= π/4 × (180°/π)

=180 /4

=45°

Hence, the measure in degrees (pi)/4 is 45°.
