The value of the x will be 109°The straight line subtended an angle of 180°. The angle is obtained by solving the equation.
What are supplementary angles?
Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles to form on each of the sides of the considered straight line.
Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
The straight line subtended an angle of 180°. The equation obtained is;
⇒x+42°+29°=180°
⇒x=109°
Hence, the value of the x will be 109°
