please fast and no more wrong answer please.


From the following figures find the value of a and b​

Answer 1

Answer:

which class question is this

Answer 2

Step-by-step explanation:

(a). CDR= DRS(Alternate angles)

SRT+DRS= 180°(Adjacent angles)

SRT=3a

CDR=a

SRT+CDR(CDR=DRS)

3a+a=180°

4a=180°

a=180°/4

a=45°

3a= 135°

SRT=135°

CDR=45°

DRS=45°

(b).ABC=BCE(alternate angles)

BCE=40°

a=40°

DCE=BEC

BCE=b

CEF+BEC=180°(linear pair)

120°+b=180°

b=60°
