Answer:
10.5 cm
Step-by-step explanation:
12÷9= 1.3 (1dp)
14÷(12÷9)= 10.5cm
Answer:
1.4
Step-by-step explanation:
Ex.: 1/2, 2 1/2, 5/3, etc. Note that 2 1/2 means two and half = 2 + 1/2 = 2.5
Answer:
D. <em>a</em> = 11.71 and <em>b</em> = 15.56
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Trigonometry</u>
- All angles in a triangle add up to 180°
<u>Pre-Calculus</u>
- Law of Sines:

Step-by-step explanation:
<u>Step 1: Define</u>
AC = b
CB = a
AB = 7
m∠A = 45°
m∠B = 110°
m∠C = ?
<u>Step 2: Find missing ∠</u>
- Set up equation: m∠C + 45° + 110° = 180°
- Combine like terms: m∠C + 115° = 180°
- Isolate unknown: m∠C = 25°
<u>Step 3: Find measure of </u><em><u>b</u></em>
- Substitute:

- Cross-multiply:

- Isolate <em>b</em>:

- Evaluate:

- Round:

<u>Step 4: Find measure of </u><em><u>a</u></em>
- Substitute:

- Cross-multiply:

- Isolate <em>a</em>:

- Evaluate:

- Round:

Distribute.
3(x+6)
3x+18
8(x-3)
8x-24
3x+18+8x-24
Combine like terms.
11x-6= 27
Add 6 to the other side.
11x= 33
Divide both sides by 11.
x=3
