Answer:
The answer should be C. By combining like terms you can find the answer. 1.75a+2.75a = 4.5a
2.25b + 1.75b = 4b
2.25c + 1.25c = 3.5c

Step-by-step explanation:
<u>Step 1: Set Up Equation</u>
(x + 7)° = (5x - 49)°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract <em>x</em> on both sides: 7 = 4x - 49
- Add 49 on both sides: 56 = 4x
- Divide 4 on both sides: 14 = x
- Rewrite: x = 14
<u>Step 3: Find angle measure</u>
- Define: (x + 7)°
- Substitute in <em>x</em>: (14 + 7)°
- Add: 21°
