Thhis is correct because you do the same for both
2. 1 pound is 16 ounces. So 12.5 x 16 = 200
Answer:
m∠B = 69°
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Complementary Angles add up to 90°
Step-by-step explanation:
<u>Step 1: Define</u>
m∠A = (x + 9)°
m∠B = (7x - 15)°
<u>Step 2: Set up equation</u>
m∠A + m∠B = 90°
(x + 9)° + (7x - 15)° = 90°
<u>Step 3: Solve for </u><em><u>x</u></em>
- Combine like terms: 8x - 6 = 90
- Add 6 to both sides: 8x = 96
- Divide both sides by 8: x = 12
<u>Step 4: Find m∠B</u>
- Define: m∠B = (7x - 15)°
- Substitute: m∠B = (7(12) - 15)°
- Multiply: m∠B = (84 - 15)°
- Subtract: m∠B = 69°
