Answer 1

Answer:

angle 1and 2 are supplementary

ratio=5:4

let first angle be 5x and second angle be4x

5x+4x=180°

9x=180°

x=180/9

x=20

5x=20*5=100°(angle 1)

4x=20*4=80(angle 2)

angle2=angle 3( corresponding angle)

angle 3=80°

angle 3 and angle 4 are supplementary

angle3+angle4=180°

80°+angle4=180°

angle4=180-80=100°

angle 3=80°, angle 4=100°
