Answer:

<em>Sin 2 (30)°=  </em>\frac{\sqrt{3} }{2}

Step-by-step explanation:

<u><em>Explanation:-</em></u>

<em>Given that   Sin 2 (30)°</em>

<em>we know that the formula  sin2θ = 2sinθ cosθ</em>

<em>    Given that θ = 30</em><em>° </em>

<em>    Now  </em>

<em>          sin2(30)° = 2sin30° cos30°</em>

<em>                                              </em>= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )<em> </em>

<em>        After cancellation, we get</em>

<em>                            Sin 2 (30)° = </em>\frac{\sqrt{3} }{2}

<u><em>Final answer:-</em></u>

<em>           Sin 2 (30)° = </em>\frac{\sqrt{3} }{2}<em>    </em>

<em></em>

Step by step solution :

Step 1 :

1
Simplify —
3
Equation at the end of step 1 :

2 1
((—•x)-7)+((—•x)+5)
3 3
Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 3 as the denominator :

5 5 • 3
5 = — = —————
1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x + 5 • 3 x + 15
————————— = ——————
3 3
Equation at the end of step 2 :

2 (x + 15)
((— • x) - 7) + ————————
3 3
Step 3 :

Simplify —
3
Equation at the end of step 3 :

2 (x + 15)
((— • x) - 7) + ————————
3 3
Step 4 :

Rewriting the whole as an Equivalent Fraction :

4.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 3 as the denominator :

7 7 • 3
7 = — = —————
1 3
Adding fractions that have a common denominator :

4.2 Adding up the two equivalent fractions

2x - (7 • 3) 2x - 21
———————————— = ———————
3 3
Equation at the end of step 4 :

(2x - 21) (x + 15)
————————— + ————————
3 3
Step 5 :

Adding fractions which have a common denominator :

5.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(2x-21) + (x+15) 3x - 6
———————————————— = ——————
3 3
Step 6 :

Pulling out like terms :

6.1 Pull out like factors :

3x - 6 = 3 • (x - 2)

Final result :

x - 2
