Question

in the given figure below ab||cd t is a transversal interesting e and f respectly if ∆2:∆1=5:4 find the measure of each marked angle

Answer 1

Hope it will help. Pls mark as brainliest

Answer 2

5x+4x=9x
9x=180
x=20
so aangle 1= 20°×4=80
angle 2= 5×20=100°
angle3= 180-100=80°
angle 4=180-80=100°
angle1=angle 7
angle2= angle 8
angle 3=angle 5
angle4=angle 6
