Answer:
150
Step-by-step explanation:
We know < 4 = 60 because corresponding angles are equal for parallel lines
We know < 3 = 90 because they are vertical angles
<3 + <4 + <5 = 180 because they from a triangle
<3 + 60+90 = 180
<3 + 150 =180
< 3 = 180-150
<3 = 30
< 3 + <2 = 180 because they form a line
30 + <2 = 180
<2 = 180-30
<2 = 150
