Answer:
144°
Step-by-step explanation:
We are asked to convert 4π/5 radians to degrees.
#We know that:

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

Hence, the degrees equivalent of 4π/5 rad is 144°.
The answer for this equation is x=2
the answer is 12 because half of the sphere is 6 unit and the other half is 6 unit then you just add them and you get 12 units
Step-by step explanation:
That's a great question. Look for things such as these:
x=x (infinite solution)
x=12 (one solution)
x+3 = x + 5 (no solutions)
