Answer:
which class question is this
Verified answer
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°
hope this helps you mark me as brainliest pls
