Answer:
x = 9
Explanation:
All angles of a triangle add to 180°.
You are give angles: 41°, 90° (the right angle indicated by the square), and (3x + 22)°
Because you easily know angles, it makes figuring the third easier.
180° - 41° - 90° = third angle should be 49°.
so:
3x + 22 = 49
subtract 22 from both sides:
3x = 27
x = 9
