Question

In the given figure AS||BT; ∠4 = ∠5 SB bisects ∠AST. Find the measure of ∠1

Answer 1

1+2+3=180
&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
