(PLEASE HELP!!) Use the following diagram to answer the questions.
monitta

Answer:

x:

5x - 29 = 3x+ 19

2x = 48

x = 24°

Angle 1:

180 - (3x+7) = 180 - 79 = 101°

Angle 2:

3x + 7 = 79°

Angle 3:

Same as Angle 1 = 101°

Angle 4:

Same as Angle 1 = 101°

Angle 5:

Same as Angle 2 = 79°

Angle 6:

Same as Angle 5 = 79°

Angle 7:

180 - (5x - 29) = 180 - 91 = 89°

Angle 8:

Same as Angle 7 = 89°

Angles 2 and 3 are Supplementary angles

Question in picture<br><br>A) 16/63<br><br>B)-16/63<br><br>C) 63/16<br><br>D) -63/16
Orlov [11]
ANSWER
\tan(x + y) =  -  \frac{63}{16}


EXPLANATION


We were given that,

\csc(x)  =  \frac{5}{3}

This implies that,

\sin(x)  =  \frac{3}{5}

We use the Pythagorean identity

\sin^{2} (x)  +  \cos^{2} (x)= 1
to get,


\cos(x)  =  \sqrt{1 - ( { \frac{3}{5} })^{2}}  =  \frac{4}{5}


We were also given that,


\cos(y)  =  \frac{5}{13}

This means that,


\sin(y)  =  \sqrt{1 -  {( \frac{5}{13}) }^{2} }  =  \frac{12}{13}

This is because,


0 <  \: x \:  <  \frac{\pi}{2}


0 <  \: y \:  <  \frac{\pi}{2}

This angles are in the first quadrant so we pick the positive values.

\tan(x + y)  =  \frac{ \sin(x + y) }{ \cos(x + y) }


\tan(x + y)  =  \frac{ \sin(x ) \cos(y)   +  \sin(y)  \cos(x) }{ \cos(x) \cos(y)  -  \sin(x)  \sin(y) }



\tan(x + y)  =  \frac{  \frac{3}{5}   \times  \frac{5}{13}  +   \frac{12}{13}   \times  \frac{4}{5}  }{  \frac{4}{5}  \times  \frac{5}{13}   -   \frac{3}{5}  \times  \frac{12}{13}  }



\tan(x + y) =  -  \frac{63}{16}

The correct answer is D

Gekata [30.6K]
Perimeter = the sum of all sides
Because we know that 2 sides are 5 inches and that 2 other sides are 4 inches long, we can subtract this number from the total 27 to get the 5th side.      5+5+4+4 = 18        27-18= 9
The fifth side = 9 inches
