Answer 2

$<b>HELLO MATE!$

(i) we know that sum of all angles of linear pair is 180°.

$\therefore$ x + 10 + x + 20 + x = 180°

=> 3x + 30 = 180

=> 3x = 180 - 30

=> 3x = 150

=> x = 150/3

=> x = 50

Therefore,

angles are : (x + 10) = (50 + 10) = 60°

2nd angle : (x + 20) = (50 + 20) = 70°

3rd angle : x = 50°

——————————————

(ii) angle AOB = AOC + COB

=> 90° = 8x + x

=> 90° = 9x

=> x = 90/9

=> x = 10
