Answer» Given: AS is parallel to BT, and SB bisects angle AST that is angle 2 = angle 3 To find: The measure of angle 1 Solution: 1+2+3=180&2=3. because SB. is the bisector 1=4. because corresponding anglesangle 4=180-(2+3). ................ [1]angle 4=180-(3+5)....................[2]From 1&2,2=5 .....................[3]Hence,1+2+3=180&3+5+4=1803*angle 3=180angle 3=60It means angle 1=60 |
