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)° = $\frac{\sqrt{3} }{2}$

Alika [10]

Step-by-step explanation :

Sam : 0.25 = $\frac{25}{100}$ = $\frac{1}{4}$ (Answer)

Mark : 0.30 = $\frac{30}{100}$ = $\frac{3}{10}$ (Answer)

Jill : 0.35 = $\frac{35}{100}$ = $\frac{7}{20}$ (Answer)

Total amount of pizza eaten = 0.25 + 0.30 + 0.35 = 0.9

Amount of pizza left = 1.0 - 0.9 = 0.1 = $\frac{10}{100}$ = $\frac{1}{10}$ (Answer)
