Select the correct answer.
makvit [3.9K]

Answer:

<h3>64°</h3>

Step-by-step explanation:

y = 52° ( Opposite Angles )

y + 2x = 180° ( Interior Angles )

y + 2x =  {180}^{o}  \\  {52}^{o}  + 2x =  {180}^{o}  \\ 2x =  {180}^{o}  -  {52}^{o}  \\ 2x =  {128}^{o}  \\ x =  \frac{ {128}^{o} }{2} \\ x =  {64}^{o}  \\

Ahmed is solving the following equation for xxx.
Dennis_Churaev [7]

Answer:

No

Step-by-step explanation:

An extraneous solution is a root of a transformed equation which is not a root of the original equation because it was not included in the domain of the original equation.

Ahmed is solving 2\sqrt[3]{x-7}+11=3 for x.

His steps were:

\begin{aligned}2\sqrt[3]{x-7}&=-8\\  \sqrt[3]{x-7}&=-4\\  \left(\sqrt[3]{x-7}\right)^3&=(-4)^3\\  x-7&=-64 \end{aligned}

Since cube roots <u>do not give two solutions when solved</u>, it is <u>not necessary </u>to check his answers for extraneous solutions.
