Answer:

error in step 1

Step-by-step explanation:

$\frac{1}{2}$ (x + 18) = 4(2x - 6) - 9x

Multiply through by 2 to clear the fraction

x + 18 = 8(2x - 6) - 18x

[ Eleanor made the error in not multiplying - 9x by 2 ] ← ←

x + 18 = 16x - 48 - 18x

x + 18 = - 2x - 48 ( add 2x to both sides )

3x + 18 = - 48 ( subtract 18 from both sides )

3x = - 66 ( divide both sides by 3 )

x = - 22

Given right triangle ABC, what is the value of tan(A)?

Angelina_Jolie [31]

You didn't provide more information regarding triangle but from given options, it seems that triangle has ratio from shortest side to longest side would be 5 : 12 : 13

So 13 would be hypotenuse since it is longest.

Now A cannot be right angle because tangent is not defined at 90°.

Also tan(A) would be ratio of opponent side to adjacent side (think SOH CAH TOA)

So either opposite side would be 5 or 12, and adjacent side would be 12 or 5 respectively.

So the answer is either 5 / 12 or 12 / 5 but only option provided is 12/5 so that would be your answer.

Final answer: 12 / 5
