9. In the given figure, ED and EF are perpendiculars
drawn on BA and BC, respectively. If angle ABC =
50°, find angle DEF.


​

Answer 1

Answer:

BFED is quadrilateral. summation of 4 angles will be 360°. angle D and angle F each is 90° angle B is 50°.that means angle E is {360°-(90°+90°+50°)}=130°
