Answer 1

Answer:

1)80 degrees

2)180 degrees

3)angle acb=58 degrees,angle bdc=122 degrees

Step-by-step explanation:

1)angle PQR=Angle SRT

Angle SRT=40 Degrees

Angle SRT+Angle STR+AngleRST=180 Degrees(angle sum property

60 Degrees+40 Degrees+Angle STR=180 Degrees

Therfore,Angle STR=80 Degrees

3)Angle ABC+AngleBCA+Angle BAC=180 Degrees(Angle sum property)

64 Degrees+58 Degrees +Angle ACB =180 Degrees

Therfore,Angle ACB=58 Degrees

BD And DC are angle bisectors of Angle ABC and Angle BCA

So,Angle DBC=58/2=29 degrees

Similarly,AngleDCB=58/2=29 Degrees

In triangle BDC,Angle BDC+Angle CBD+Angle DCB=180 Degrees

29 Degrees+29 Degrees+Angle BDC=180 Degrees

Therefore Angle BDC=122 Degrees
