Answer:
38°
solution,
<2=38°( being corresponding angles)
<4=<2( being vertically opposite angles)
=38°
About corresponding angles:
Please look the first one picture.
There,
<b is an exterior and <d is an interior angle lying to the same side of transversal and they are not adjacent to each other.They are called corresponding angle.A pair of corresponding angles made by a transversal with parallel lines is always equal.
About vertically opposite angles
please look the second one picture.
there,
<AOC and <BOD are formed by intersected line segments and they lie to the opposite side of common vertex.They are called vertically opposite angles.<AOD and <BOC are another pairs of vertically opposite angles.Vertically opposite angles are always equal.
<AOC=<BOD
<AOD=<BOC
Hope this helps...
Good luck on your assignment..
