The angle by which ab turns clockwise about point b to coincide with bc is ? degrees. if from point b, a point e is drawn directly opposite point c so that b, e, and c are on the same straight line, the angle by which ab turns counterclockwise to coincide with be is ? degrees.
fill in the ? marks

Step-by-step explanation:

We have the statement AB turns clockwise to coincide with BC.

= ABD + DBC

= 33.3° + 30.6°  

= 63.9°

Now we have the statement a point E is drawn directly opposite point C. B, E, and C are on the same straight line

EBC is a straight line, so sum of angles =180°

ABE + ABD + DBC = 180°

ABE + 33.3° + 30.6° = 180°

ABE + 63.9° = 180°

ABE = 180 - 63.1

ABE = 116.9°

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
