Question

HELP!!find the measures of the angles in triangle EDB.

angle EBD = 22.5º; angle BDE = 90º; angle DEB = 68.5º
angle EBD = 45º; angle BDE = 22.5º; angle DEB = 112.5º
angle EBD = 45º; angle BDE = 45º; angle DEB = 90º
angle EBD = 22.5º; angle BDE = 45º; angle DEB = 112.5º

Answer 7

Thank you @RadEn. and can you help me with this one: find the measures of the angles in triangle EDB.

angle EBD = 22.5º; angle BDE = 90º; angle DEB = 68.5º
angle EBD = 45º; angle BDE = 22.5º; angle DEB = 112.5º
angle EBD = 45º; angle BDE = 45º; angle DEB = 90º
angle EBD = 22.5º; angle BDE = 45º; angle DEB = 112.5º

Answer 8

BDE = 45/2 = 22.5
EBD = 45
DEB = 180 - (22.5 + 45) = 180 - 67.5 = 112.5
