m27 = [ ? 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)`
