Answer 1

Answer:

Hope this helps you :)

3x + 20° + 2x - 10° = 180° ( Linear pair )

5x + 10° = 180°

5x = 170°

x = 170/5

x = 34°

Angle AOC = 3x + 20° = 3(34) + 20 = 122°

Angle BOC = 2x - 10° = 2(34) - 10 = 58° :)

Answer 2

Answer:

Step-by-step explanation:

$(3x + 20) + (2x - 10) = 180 deg (supplementary angles)\\3x + 20 + 2x - 10 = 180 deg \\5x + 10 = 180 deg\\5x = 180 -10\\5x = 170 deg\\x = 170/5\\x = 34 deg$

Therefore, (3x + 20) is 122 deg and (2x - 10) is 58 deg.

Hope my answer will help
