Answer 1

PLEASE MARK AS BRAINLIST

Answer 2

Answer:

100 degrees , 80 degrees

Step-by-step explanation:

SOLUTION:

Given,

The adjacent angle of a ||gm in ratio=5:4

Let the ratio be x

$5x + 4x = 180^o(adjacent angle)\\\\9x = 180^0\\\\x = \frac{180}{9} \\\\x = 20$

 Now,

1st angle = 5x, 5× 20° = 100°

2nd angle= 4x, 4×20°= 80°

hope it helps ☺️
