Answer:
x = 34
Step-by-step explanation:
90° + 42° = 132°
180° - 132° = 48°
m∠DFE = 48°
2x + 48 + 64 = 180
2x + 112 = 180
2x = 68
x = 34
Answer:
c = 6
Step-by-step explanation:
Step 1: Write equation
2(5c + 2) - 2c = 3(2c + 3) + 7
Step 2: Solve for <em>c</em>
- Distribute: 10c + 4 - 2c = 6c + 9 + 7
- Combine like terms: 8c + 4 = 6c + 16
- Subtract 6c on both sides: 2c + 4 = 16
- Subtract 4 on both sides: 2c = 12
- Divide both sides by 2: c = 6
My guess is 30 mins sorry if wrong hope this helps
