Find the value of sin θ, if tan θ=4; 180° < θ <270°
Nana76 [90]
You can use the identity
\sin(x)=\sqrt{\dfrac{\tan(x)^{2}}{1+\tan(x)^{2}}}\\\\=-\sqrt{\dfrac{4^{2}}{1+4^{2}}}\\\\=-\sqrt{\dfrac{16\cdot 17}{17\cdot 17}}=\dfrac{-4\sqrt{17}}{17}

The sign is negative because the angle is in the 3rd quadrant.

This corresponds to ...

RS=2x-8, ST = 11, RT = x+10
ziro4ka [17]

Answer:

Equation~=~\Large\boxed{2x+3=x+10}

x~=~\Large\boxed{7}

RS~=~\Large\boxed{6}

RT~=~\Large\boxed{17}

Step-by-step explanation:

<u>Given information</u>

RS=2x-8

ST=11

RT=x+10

<u>Derived expression from the given information</u>

<em>Presumably, I think this is a combination of segments</em>

RS+ST=RT

<u>Substitute values into the given expression</u>

(2x-8)+(11)=(x+10)

<u>Combine like terms</u>

<em>The following is the expression</em>

\Large\boxed{2x+3=x+10}

<u>Subtract 3 on both sides</u>

2x+3-3=x+10-3

2x=x+7

<u>Subtract x on both sides</u>

2x-x=x+7-x

\Large\boxed{x=7}

<u>Substitute the x value into corresponding expressions to determine the final value</u>

RS=2x-8=2(7)-8=14-8=\Large\boxed{6}

RT=x+10=(7)+10=\Large\boxed{17}

Hope this helps!! :)
