Sagot :

Answer:

C) 140

Step-by-step explanation:

You will need to find angles 1, 2 and 3 to get 4

Angle 3 is on the same line as 6 and supplementary, forming 180.

Therefore, substract angle 6 from 180 to get 3

180 = Angle 6 + Angle 3

180 - 120 = Angle 3

60 = Angle 3

Angle 2 is the same concept

180 - 100 = 80

80 = Angle 2

Angle 1

All angles in the triangle are 180, therefore, angle 1 is found using

180 - Angle 2 -Angle 3 = Angle 1

180 - 80 - 60 = Angle 1

40 = Angle 1

And since Angle 1 and 4 are on the same line, supplemantary and forming 180, substract angle 1 from 180 to get angle 4

180 = Angle 1 + Angle 4

180 - 40 = Angle 4

140 = Angle 4
