Sagot :

The angle measures are;

Angle 7  is 40° = Angles 8 : supplementary

Angle 3 is 40° = Angles 8: supplementary angles

Angle 5 = 140°  = Angle 8; corresponding angles

Angle 1 = 140°  = Angle 8; corresponding angles

Angle 6 = 40°  = Angle 8; supplementary angles

Angle 2 = 140°  =  Angle 8; corresponding angles

Angle 4 = 140°  Angle 8; corresponding angles

How to determine the angles

Given that angle 8 measures 140 degrees

It is important to note that angles on a straight line equals 180 degrees

Then,

angle 7 + angle 8 = 180°

Substitute the values of angle 8

Angle 7 + 140 = 180

Angle 7 = 180 - 140

Angle 7 = 40°

Thus, If angle 7  is 40° then angle 3 is 40°, corresponding angles

Angle 5 = Angle 8; corresponding angles

Angle 1 = Angle 8; corresponding angles

Angle 6 = Angle 7; corresponding angles

Angle 2 = Angle 8; corresponding angles

Angle 4 = Angle 8; corresponding angles
