In the picture, line AC is perpendicular to line BE. The angle adjacent to ∡ABE is ∡FBC.
The angle complementary to ∡EBD is ∡ABD.
If the measure of ∡DOE = 40°, the measure of ∡COB is 90°.
If the measure of ∡DOE = 40°, the measure of ∡EOA is 50°.
The measure of the labeled angles in the picture are not given in the question, so it cannot be determined.
The answers are:
1. ∡EBF
2. ∡EBC
3. 50°
4. 90°
5. 30°
