Answer:
x = 22
Step-by-step explanation:
Step 1: Write equation
2(x + 9) = 4(x - 7) + 2
Step 2: Solve for <em>x</em>
- Distribute: 2x + 18 = 4x - 28 + 2
- Combine like terms: 2x + 18 = 4x - 26
- Subtract 2x on both sides: 18 = 2x - 26
- Add 26 to both sides: 44 = 2x
- Divide both sides by 2: 22 = x
- Rewrite: x = 22
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
2(22 + 9) = 4(22 - 7) + 2
2(31) = 4(15) + 2
62 = 60 + 2
62 = 62
It’s 100 because it shows the angle is a 90 degree angle
Answer:
x = 5.57
Step-by-step explanation:
c² = a² + b² − 2ab cos C
x² = 10² + 6² − 2(10)(6) cos 29°
x = 5.57
Your answer and steps are correct.
I really can’t answer this one sorry I’m confused as well
