B. 120. the reason is :- 1) sum of linear pair of angles is 180, and 2) sum of the angles of a triangle is 180.

180-100= 80 gives the second angle of the triangle. 40+80= 120= Exterior angle, hence B

OR

We know the third angle on the line is 60, hence the complimentary exterior angle would be 120. Hence, B.

IMO B-120.
100 degrees = 40deg +(180-x)deg
x= 120 degrees.
Primary rule used : External angle of a triangle is equal to the sum of its two opposite internal angles.

Let the unknown angles inside the triangle be \(y\) and \(z\).

\(y + z + 40 = 180\) -------- (i)

Straight line has angles from left to right \(100^{\circ}\), \(y^{\circ}\) , \(z^{\circ}\) and \(x^{\circ}\) respectively.

Straight line has angle equal to \(180^{\circ}\).

\(100 + y = 180\)

\(y = 180 - 100 => 80\)

Substituting value of \(y\) in (i), we get;

\(80 + z + 40 = 180\)

\(120 + z = 180\)

\(z = 180 - 120 => 60\)

Straight line has angle equal to \(180^{\circ}\).

\(z + x = 180\)

\(60 + x = 180\)

\(x = 180 - 60 => 120\)

Answer (B)...
