Question

In the adjoining figure,AB//CD are cut by a transversal t at E and F respectively. If angle 2 :angle 1 = 5:4, find the measure of each one of the marked angles.

Answer 1

angle 2 + angle 1   =  180 deg.
as the angles are   in 5 : 4 ratio...  

  angle 2 = 5/9 * 180 = 100 deg
  angle 1 = 4/9 * 180 = 80 deg

----

Answer 2

Answer:

Step-by-step explanation:

angle 2+ angle 1= 180°

Since, 5 : 4,

angle 2 = 5/9 x 180 = 100°

angle 1 = 4/9 x 180 = 80°
