Question

85. Pair of interior angles formed when a pair of parallel lines are intersected by a transversal are 2x and 3xº. Then their measures are = ? (1) 720, 108° (2) 1440, 36 (3) 108°, 62° (4) 120°, 60°​

Answer 1

Answer:

2x+3x=180

5x=180

x=180÷5

x=36

So,2x=2×36=72

3x=3×36=108

Thus, (72,108) is the right answer.
