X 2x+24<br> Please help me I don’t know what to do
valkas [14]

Answer:

x = 52°

Also, you can use this formula for any other angles. For example, input 90° instead of 180°. I have a feeling that you didn't understand this before. Maybe this will help.

Step-by-step explanation:

180° = x+2x+24°

180° = 3x° + 24°

180° - 24° = 3x

156° = 3x

x = 52°
