Answer:

  • Error in step 2 and step 3, corrected below

Step-by-step explanation:

<u />

<u>Step                |   Justification</u>  

6 + x/3 = 15     |   Given                                                                                        

x/3 = 15           |   Subtract 6 from each side. Should be subtraction property

x = 27              |   Multiply both sides by 3. Should be multiplication property

Answer:

( 6, pi/6)

Step-by-step explanation:

( 3 sqrt(3), 3)

To get r we use x^2 + y ^2 = r^2

( 3 sqrt(3) )^2 + 3^2 = r^2

9 *3 +9 = r^2

27+9 = r^2

36 = r^2

Taking the square root of each side

sqrt(36) = sqrt(r^2)

6 =r

Now we need to find theta

tan theta = y/x

tan theta = 3 / 3 sqrt(3)

tan theta = 1/ sqrt(3)

Taking the inverse tan of each side

tan ^-1 ( tan theta) = tan ^ -1 ( 1/ sqrt(3))

theta = pi /6
