Given: l | | m
m∠4 = 105° and m∠6 = 50°.
m∠2 =
50°
55°
75°

Answer:
x = 55°
Step-by-step explanation:
<4 = 105
<4 + <3 = 180 (supplementary angles, form a line)
180-105= 75
<3 = 75
The interior angles of a triangle always equal 180 degrees.
<3 = 75 degrees, <6 = 50, <2 = x
75+50+x = 180
125 + x = 180
x = 55°
