  • Addition Property of Equality
  • Subtract Property of Equality

<u>Pre-Calculus</u>

Law of Sines: \displaystyle \frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}

  • A, B, C are angle measures
  • a, b, c are leg lengths

Step-by-step explanation:

<u>Step 1: Identify</u>

A = 27°, a = 11

B = x°, b = 15

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [LOS]:                     \displaystyle \frac{sin(27^{\circ})}{11} =\frac{sin(x^{\circ})}{15}
  2. Cross-multiply:                        \displaystyle 11sin(x^{\circ}) = 15sin(27^{\circ})
  3. Isolate <em>x</em> term:                         \displaystyle sin(x^{\circ}) = \frac{15sin(27^{\circ})}{11}
  4. Isolate <em>x</em>:                                  \displaystyle x = sin^{-1}(\frac{15sin(27)}{11})
  5. Evaluate:                                 \displaystyle x = 38.2488 ^{\circ}
  6. Round:                                    \displaystyle x \approx 38.2 ^{\circ}
