Question

Lines A and B are parallelA155°3 4B.5 67 8m27 = [ ? 1°

Answer 1

It is given that two lines A and B are parallel.

The one angle given is , 55 deg.

From the alternate opposiye angles,

$\angle3=55^{\circ}$

And from the corresponding angles property, the angle 3 is corresponds to angle 7.

$\angle3=\angle7=55^{\circ}$

Hence the value of angle 7 ,

$m\angle7=55^{\circ}$
