How many sides does a regular polygon have if each of its interior angle measures 120 degree​
alekssr [168]
6 sides .

If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.

Solve sin2theta=2sinthetacostheta​
pashok25 [27]

Answer:

\sin(2\theta) =2 \sin \theta \cos \theta proved

Step-by-step explanation:

Given

\sin2 \theta=2 \sin\theta cos\theta

Required

Prove

Proving from left to right.

\sin(2\theta) = \sin(\theta+\theta)

In trigonometry

\sin(A+B) = \sin A \cos B+\sin B \cos A

When this formula is applied to:\sin(2\theta) = \sin(\theta+\theta)

We have:

\sin(2\theta) = \sin \theta \cos \theta+\sin \theta \cos \theta

\sin(2\theta) =2 \sin \theta \cos \theta
