Answer 1

Answer:

Given = <2:<1 = 5:4

To find : all angles

Explanation :

Let the angle be x

thus

5x+4x = 180 (linear pair)

9x = 180

x = 20°

now,

5x = 5×20 = 100°

4x = 4×20 = 9 = 80°

from the figure,

<1 = <3 = <5 = <7 = 80°(alternate interior angles)

<2 = <4 = <6 = <8 = 100°

(alternate interior angles)
