Answer:
a = 60°
60°, 60°, 120°, and 120°.
Step-by-step explanation:
Sum of interior angles of a quadrilateral = 360°
Therefore:
a° + a° + 2a° + 2a° = 360°
Add like terms
6a = 360
Divide both sides by 6
a = 60
2a = 2(60) = 120°.
Angle measure from least to greatest are 60°, 60°, 120°, and 120°.
Answer:
-4
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
1. Distribute: -3x + 6x + 3 = x-1
2. Combine like terms: 3x + 3 = x-1
3. Subtract 3 on both sides: 3x = x-4
4. Subtract x on both sides: 2x = -4
5. Divide each side by 2: x = -2
6. Check by plugging in -2 to the equation:
