Answer:

Answer: 50 degrees

Explanation:

important things to know:

  • the square in the bottom right means 90°
  • all angles in a triangle add up to 180°

using this knowledge, you can make the following equation:

90 + 40 + x = 180

130 + x = 180

now subtract 130 from both sides.

x = 180 - 130

x = 50°
