Question

What ia the angle of AOC and DOE

Answer 1

(i) Angle AOC would equal 48°, as it is vertically opposite to angle DOB and they are therefore equal.

(ii) Angle DOE would equal 42°. We can see this because angles on a straight line add up to 180°, and 90 + 48 = 138, so we can do 180 - 138 = 42°.

I hope this helps!
