Question

List the order to write and solve the equation for X:

Angle 1: 45°
Angle 2: (8x+21)°
It has a square on the lower right hand side.

1. Divide both sides of the equation by 8
2. Combine like terms: 45+90+21
3. subtract 156 from both sides of the equation
4. Write the equation angle 1 + angle 2 + angle 3 = 180°
5. X = 3

Answer 1

The correct order to write and solve the equation for X is:

1. Write the equation: Angle 1 + Angle 2 + Angle 3 = 180°
2. Substitute the given values: 45° + (8x + 21)° + 90° = 180°
3. Combine like terms: 135° + 8x + 21° = 180°
4. Combine like terms again: 156° + 8x = 180°
5. Subtract 156° from both sides of the equation: 8x = 24°
6. Divide both sides of the equation by 8: x = 3

Answer 3

Based on the provided answer choices, the correct order to write and solve the equation for X is:

1. Write the equation: Angle 1 + Angle 2 + Angle 3 = 180°
2. Substitute the given values: 45° + (8x + 21)° + 90° = 180°
3. Combine like terms: 135° + 8x + 21° = 180°
4. Subtract 156° from both sides of the equation: 8x = 180° - 156°
5. Combine like terms: 8x = 24°
6. Divide both sides of the equation by 8: x = 3
