and BC become parallel.​

Answer 1

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

Step-by-step explanation:

and 2=3. because SB. is the bisector

1=4. because corresponding angles

angle 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=180

3*angle 3=180

angle 3=60

It means angle 1=60.
