Answer:

  12 or 103

Step-by-step explanation:

The given angle is opposite the shorter side, so there will be two solutions.

In order to find f, we need to know angle F. We can find that by first finding angle E.

  E = arcsin(e/d·sin(D)) = arcsin(71/62·sin(36°)) = 42.307° or 137.693°

  F = 180° -D -E = 180° -36° -{42.307°, 137.693°} = {101.693°, 6.307°}

Then the measure of f is ...

  f = sin(F)/sin(D)×d = 62/sin(36°)×sin({101.693°, 6.307°})

  f = {103.29, 11.59}

Side f is either 12 or 103.

Answer:

  • 103

Step-by-step explanation:

Find ∠E

  • sin E / 71 = sin 36° / 62
  • sin E = 71 (sin 36°) / 62
  • sin E = 0.673
  • m∠E = arcsin (0.673)
  • m∠E =  42° (rounded)

Find m∠F

  • m∠F = 180° - (36° + 42°) = 102

Find f

  • sin 102° / f = sin 36° / 62
  • f = (62 sin 102°) / (sin 36°)
  • f = 103 (rounded)
