Question

Transforme em graus 3π/4

Answer 1

Ola Quilo

π = 180°

x = 3*180/4 = 135° 

Answer 2

π rad ----------------- 180°

$\frac{3 \pi }{4}$ rad ----------------- x°

Multiplicando na diagonal

xπ = 180 * $\frac{3 \pi }{4}$

xπ = $\frac{540 \pi }{4}$

xπ = 135π

x = $\frac{135 \pi }{ \pi }$

x = 135

Logo 

$\frac{3 \pi }{4}$ = 180°
