Question

Two adjacent angles of a parallelogram are in the ratio 1:5. Then all
the angles of the parallelogram are
(a) 30°, 150°, 30°, 150°
(b) 85°, 95°, 85°, 95°
(c) 45°, 135°, 45°, 135°
(d) 30°, 180°, 30°, 180°

Answer 1

Answer:

Let the adjacent angles of a parallelogram be x and 5x, respectively. Then, x + 5x = 180° [ adjacent angles of a parallelogram are supplementary] => 6x = 180° => x = 30° The adjacent angles are 30° and 150°. Hence, the angles are 30°, 150°, 30°, 150°Read more on Sarthaks.com - https://www.sarthaks.com/850187/two-adjacent-angles-parallelogram-are-the-ratio-then-all-the-angles-the-parallelogram-are
