Question

in the figure , if l parallel m ; n parallel p and angle 1 =85 degrees find angle 2 ,angle 3
​

Answer 1

Answer:

angle 2 =95 degree

Step-by-step explanation:

Given: ∠1 = 85°  As we know, when a line cuts the parallel lines, the pair of alternate interior angles are equal.  ∠1 = ∠3 = 85°  Again, co-interior angles are supplementary, so ∠2 + ∠3 = 180° ∠2 + 55° = 180° ∠2 = 180° – 85°  ∠2 = 95°
