Answer:

$\theta=30\textdegree$

Step-by-step explanation:

$(ii)\ \sqrt{3}\tan\ \theta=2\sin \theta\\\\substitute\ \tan\theta=\frac{\sin\theta}{\cos\theta}\\\\\sqrt{3}\frac{\sin\theta}{\cos\theta}=2\sin\theta\\\\Divide\ both\ sides\ by\ \sin\theta.\\\\\sqrt{3}\frac{\sin\theta}{\cos\theta\times \sin\theta}=\frac{2\sin\theta}{\sin\theta}\\\\\frac{\sqrt{3}}{\cos\theta}=\frac{2}{1}\\\\Apply\ cross\ multiplication\\\\2\cos\theta=\sqrt{3}\\\\divide\ both\ sides\ by\ 2\\\\\frac{2\cos\theta}{2}=\frac{\sqrt{3}}{2}\\\\\cos\theta=\frac{\sqrt{3}}{2}\\\\$

$\cos\theta=\cos\ 30\textdegree\\\\\theta=30\textdegree$

N76 [4]

Answer:

18cm

Step-by-step explanation:

20/10 = 2cm

So since 2x10 is 20 and it exceeded only 10%, we only subtract 2 from 20 which you leave you with 18cm.

-4 × ( +1 - -5 ) × ( +1 - -5 ) ÷ 6 - ( +42 - -5 ) =

polet [3.4K]

Answer:

-71

Step-by-step explanation:

- 4 x (+1 --5) x (+1 - -5) /6 - (42 - -5)

1 - -5 = 6 and 42 - -5 = 47

-4 x 6 = -24

-24 x 6 = -144

-144 / 6 = -24

-24 - 47 = -71
