Question

Convert the angle \theta=\dfrac{8\pi}{9}θ=

Answer 1

Answer:

160°

Step-by-step explanation:

-Given the angle in radians as $\theta=\dfrac{8\pi}{9}\ rad$

-We know that  $1 \ rad=\frac{180}{\pi}\textdegree$

-Let our angle theta be X

#We therefore equate and cross multiply:

$1\ rad=\frac{180}{\pi}\\\\\frac{8\pi}{9}=x\\\\\therefore X=\frac{180}{\pi}\times \frac{8\pi}{9}\\\\=160\textdegree$

Hence, angle θ is 160°
