Answer:

Angles are: 0°, 180°, 360°, 540°

Explanation:

we have to tell four angles whose tangent equals 0.

i.e if
\tan\theta=0

we have to find 4 values of
\theta


\theta= tan^(-1)0


\theta = n\pi where n is integer

Put k=0, 1, 2, 3

n=0,
\theta = 0^(\circ)

n=1,
\theta = 180^(\circ)

n=2,
\theta = 360^(\circ)

n=3,
\theta = 540^(\circ)

Angles are: 0°, 180°, 360°, 540°

If tan α = 0
α = tan^(-1) 0
α = k π , k ∈ Z ( any integer ), π = 180°
0 · 180° = 0
1 · 180° = 180°
2 · 180° = 360°
3 · 180° = 540°
Answer:
Angles are: 0°, 180°, 360°, 540°.
