Answer:
Your answers are right.
Explanation:
Angle2 and Angle5 are same-side interior, so they are supplementary.
Showing work definitely includes writing and solving an equation and can also include using theorems and definitions as justifications.
mAngle2 + mAngle5 = 180
136° + 4x = 180°
-136° -136°
4x = 44
/4 /4 Divide by 4
x = 11
Angle5 = 4x = 4(11)
= 44°
Angle7 = Angle5 by Vertical angles.
Angle7 = 44°
Angle3 = Angle5 by Alternate Interior angles.
Angle3 = Angle1 by Vertical angles
Angle3 = 44°
Angle1 = 44°
Angle4 = Angle2 by
Vertical angles.
Angle4 = 136°
Angle8 = Angle4 by corresponding angles.
Angle8 = 136°
Angle6 = Angle8 by Vertical angles
Angle6 = 136°
