Find Sin 2 (30degrees)

Vinvika [58]

Answer:

Sin 2 (30)°= $\frac{\sqrt{3} }{2}$

Step-by-step explanation:

Explanation:-

Given that Sin 2 (30)°

we know that the formula sin2θ = 2sinθ cosθ

Given that θ = 30°

Now

sin2(30)° = 2sin30° cos30°

$= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )$

After cancellation, we get

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

Final answer:-

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

Answer:

infinite solutions

Distributive Property

Step-by-step explanation:

5x + 3(x − 5) = 6x + 2x − 15

Distribute

5x+3x -15 = 6x+2x -15

Combine like terms

8x -15 = 8x-15

Subtract 8x from each side

8x-8x-15 = 8x-8x-15

-15=-15

This is always true so there are infinite solutions

We used the Distributive Property

And the Subtraction Property of Equality
