Find 2 common angles that sum to (17pi/12) 2. Evaluate tan(17pi/12) using the sum identity for tangent.

Dmitry [639]

Note that
$\frac{17 \pi }{12} = \frac{3 \pi }{12} + \frac{14 \pi }{12} = \frac{ \pi }{4} + \frac{7 \pi }{6}$

Note that
$x= \frac{ \pi }{4}:\,\, sin(x) =cos(x)= \frac{1}{ \sqrt{2} },\,tan(x)=1\\x= \frac{7 \pi }{6} :\,\,sin(x)=- \frac{1}{2} ,\,\,cos(x)=- \frac{ \sqrt{3} }{2} ,\,\,tan(x)= \frac{1}{ \sqrt{3} }$

Use the identity
$tan(x+y)= \frac{tan(x)+tan(y)}{1-tan(x)tan(y)}$

Therefore
$tan( \frac{17 \pi }{12} )= \frac{1+ \frac{1}{ \sqrt{3} } }{1- \frac{1}{ \sqrt{3} } } = \frac{ \sqrt{3}+1 }{ \sqrt{3}-1} = \frac{( \sqrt{3}+1 )^{2}}{( \sqrt{3}-1 )( \sqrt{3}+1 )} = \frac{3+1+2 \sqrt{3}}{3-1} =2+ \sqrt{3}$

action bar. John has $132.55 in his bank account. He wants to join a guitar class that charges a $15 fee every week. John plans

Artemon [7]

$132.55-($15*12)=$132.55-$180=$-47.45
So then he would have owed 47.45 dollars!

Which equations have the same value of x as Two-thirds (6 x + 12) = negative 24? Select two options.

Anna71 [15]

Answer:

4x+8=-24 and

4x=-32

Step-by-step explanation:

2/3(6x+12)=-24

or,12x+24=-72

or,x=-72-24/12

•°•x=-8

4x+8=-24

or,x=-24-8/4

•°•x=-8

4x=-32

or,x=-32/4

•°•x=-8
