Question

Helppp geometryyyyy.

Answer 1

Solution,

Explanation:

20x+11+9x-5=180° (being linear pair)

or, 29x+6=180

or, 29x=180-6

or, 29x=174

or, x=174 ÷29

Therefore x=6°

Answer 2

x = 6

Explanation:

20x + 11 + 9x - 5 = 180 ( linear pair)

29x + 6 = 180

29x = 180-6

29x = 174

x = 6

hence angles are:

20(6) + 11 = 131

9(6) - 5 = 49
