Explanation:

Answer 2

Here's your solution

=> Both angles are interior angles hence their

=> sum will equal to 180°

=> (2x + 10)° + ( x + 5) = 180°

=> 2x + 10° + x + 5° = 180°

=>.3x + 15° = 180°

=> 3x = 180° - 15°

=>. 3x = 165°

=>. x = 165/3

=>. x = 55°

=> hence angle = 120° and 60°

hope it helps
