Step-by-step explanation:

Answer:

cos A =[tex]\frac{15}{17}[/tex]

tan A = [tex]\frac{8}{15}[/tex]

cosec A = [tex]\frac{17}{8}[/tex]

sec A = [tex]\frac{17}{15}[/tex]

cot A = [tex]\frac{15}{8}[/tex]

Step-by-step explanation:

Given sin A = [tex]\frac{8}{17}[/tex]

we know, sin A = [tex]\frac{perpendicular(P)}{hypotenuse(H)}[/tex]

using the Pythagoras theorem,

   [tex]hypotenuse^{2} =base^{2} +perpendicular^{2}[/tex]

  [tex]17^{2} =8^{2} +base^{2}[/tex]

[tex]base^{2} =17^{2} -8^{2} \\base^2= 289-64\\base^2=225[/tex]

we have,

  base (B) = 15

Now, cos A = [tex]\frac{B}{H}[/tex] = [tex]\frac{15}{17}[/tex]

        tan A = [tex]\frac{P}{B}[/tex] = [tex]\frac{8}{15}[/tex]

       sec A = [tex]\frac{1}{cos A}[/tex]  = [tex]\frac{17}{15}[/tex]

     cosec A = [tex]\frac{1}{sin A}[/tex] = [tex]\frac{17}{8}[/tex]

    cot A = [tex]\frac{1}{tan A}[/tex] = [tex]\frac{15}{8}[/tex]

Answer:

-7x³ -2x² +3x +7

Step-by-step explanation:

Let us take the unknown number as xx + 5x² - 3x + 1 = 3x² - 7x³ +8

x= 3x² - 7x³ +8 - (5x² - 3x + 1)

x=3x² - 7x³ +8 -5x² + 3x -1

x= -7x³ + 3x² - 5x² + 3x -1 + 8

x=-7x³ -2x² + 3x +7
