What is the value of x?<br><br><br><br> Enter your answer in the box.<br><br> x =
Oliga [24]

\star \blue{ \frak{To \: find :}}

\\  \\

  • value of x

\\  \\

\star \blue{ \frak{solution:}}

\\  \\

So to find value of x , we have to apply Linear Pair.

\\  \\

<u>Equation formed:</u>

\\  \\

\bigstar \boxed{ \tt(10x - 20) \degree + (6x + 8)\degree = 180 \degree}  \\

\\  \\

<u>Step by step expansion:</u>

\\  \\

\dashrightarrow  \sf(10x - 20) \degree + (6x + 8)\degree = 180 \degree \\

\\  \\

\dashrightarrow  \sf10x - 20 \degree + 6x + 8\degree = 180 \degree \\

\\  \\

\dashrightarrow  \sf10x +6x- 20 \degree  + 8\degree = 180 \degree \\

\\  \\

\dashrightarrow  \sf16x- 20 \degree  + 8\degree = 180 \degree \\

\\  \\

\dashrightarrow  \sf16x- 12\degree = 180 \degree \\

\\  \\

\dashrightarrow  \sf16x = 180 \degree + 12\degree\\

\\  \\

\dashrightarrow  \sf16x =192\degree\\

\\  \\

\dashrightarrow  \sf \: x = \frac{192\degree}{16\degree} \\

\\  \\

\dashrightarrow  \sf \: x = 12  \degree

\\  \\

\therefore \underline {\textsf{\textbf{Value of x is \red{12\degree}}}}
