Question

If one of the interior angle formed by transversal of two parallel lines is 20° more than three time the

other then the angles are ________.

(A) 20°, 160° (B) 40°, 140° (C) 60°, 120° (D) 50°, 130°​

Answer 1

Answer:

The correct answer is option(B) 40°, 140°

Step-by-step explanation:

Let one angle=x°

Another angle=(3x+20)°

Then (3x+20)°+x°=180°

4x°=160°

x°=40°

Then one angle=40° & another angle=(3×40+20)°

=140°
