Question

Trigonometry

Answer 1

Answer:

144°

Step-by-step explanation:

We are asked to convert 4π/5 radians to degrees.

#We know that:

$1 \ rad= 57.296\textdegree =180/\pi$

Therefore, we multiply 4π/5 radians  by 180/π to get its degrees equivalent:

$=\frac{4\pi}{5}\ rad\times \frac{180}{\pi}\\\\=144\textdegree$

Hence, the degrees equivalent of 4π/5 rad is 144°.
