Which line shows the first error in the solution?

<h3>Answer:</h3>

The first line.

<h3>Step-by-step explanation:</h3>

If we let x represent "a number", then "a number divided by 3" is x/3. The denominator is missing on the first line.

Further, this "is 4 more than -11", so is = 4 + (-11). The constant 4 is on the wrong side of the equal sign in line 1.

_____

The solution should be ...

... x/3 = 4 + (-11)

... x = 3·(-7)

... x = -21

___

<u><em>Check</em></u>

-21 divided by 3 is -7. That is 4 more than -11.

Answer:

cos\theta=\sqrt{\frac{85}{121}}

tan\theta=\frac{6}{\sqrt{85}}

Step-by-step explanation:

given, sin\theta=\frac{6}{11}

since, sin^2\theta+cos^2\theta=1

cos^2\theta=1-sin^2theta

cos^2\theta[/tax]=1-[tex]\frac{36}{121}

                                 =\frac{121-36}{121}

                                 =\frac{85}{121}

cos\theta=\sqrt{\frac{85}{121}} answer

tan\theta=\frac{sin\theta}{cos\theta}

  tan\theta=\frac{6}{\sqrt{85}}  answer
