Explanation:


we \: know \: that \: sum \: of \: angles \: in \: a \: line \: = 180 \\ so \\ x + 31 + x + 20 + x = 180 \\ 3x + 51 = 180 \\ 3x = 180 - 51 \\ 3x = 129 \\ x = (129)/(3) \\ x = 43degree \\ thank \: you

Answer:-


\pink{\bigstar} The measure if x
\large\leadsto\boxed{\tt\purple{43^(\circ)}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

To Find:-

  • Measure of
    \angle x

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Solution:-

The given angles are made by a straight line. We know that the total angle made by a straight line is 180°.

Therefore, all the angles should sum upto 180°.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Working:-


\sf (x + 31^(\circ)) + (x + 20^(\circ)) + (x) = 180^(\circ)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf x + 31^(\circ) + x + 20^(\circ) + x = 180^(\circ)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf 3x + 51^(\circ) = 180^(\circ)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf 3x = 180^(\circ) - 51^(\circ)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf 3x = 129^(\circ)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\sf x = (129)/(3)

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀


\large{\bold\red{x = 43^(\circ)}}

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the measure of the x is 43°.
