Calculate the side lengths a and b to two decimal places.

navik [9.2K]

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: $\frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}$

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: $\frac{sin(25)}{7} =\frac{sin(110)}{b}$
Cross-multiply: $bsin(25)=7sin(110)$
Isolate <em>b</em>: $b=\frac{7sin(110)}{sin(25)}$
Evaluate: $b=15.5645$
Round: $b \approx 15.56$

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

Substitute: $\frac{sin(25)}{7} =\frac{sin(45)}{a}$
Cross-multiply: $asin(25)=7sin(45)$
Isolate <em>a</em>: $a=\frac{7sin(45)}{sin(25)}$
Evaluate: $a=11.7121$
Round: $a \approx 11.71$

Does anyone know the answer to K+13=2+17

Sveta_85 [38]

<h3>Hello there!</h3><h3>Explanation:</h3>

In this case, you would be solving for K.

K + 13 = 2 + 17

- 13 - 13

K = -13 + 2 + 17

Combine all the like terms (add and subtract)

K = -13 + 2 + 17

K = -11 + 17

K = 6

When you see questions like this, you would want to get the variable (K) by itself.

<h3>I hope this helps!</h3><h3>Best regards,</h3><h3>MasterInvestor</h3>
