Question mark 1: Match the triangle to correct function and answer
postnew [5]

Answer:

Triangle 1 - m\angle A = 58^{\circ}, hypotenuse = 16

x \approx 8.479

Triangle 2 - m \angle A = 44^{\circ}, adjacent leg = 18

x \approx 17.382

Triangle 3 - m\angle A = 49^{\circ}, opposite leg = 12

x \approx 15.900

Step-by-step explanation:

Each triangle is solved by means of trigonometric relations:

Triangle 1 - m\angle A = 58^{\circ}, hypotenuse = 16

\cos 58^{\circ} = \frac{x}{16}

x = 16\cdot \cos 58^{\circ}

x \approx 8.479

Triangle 2 - m \angle A = 44^{\circ}, adjacent leg = 18

\tan 44^{\circ} = \frac{x}{18}

x = 18\cdot \tan 44^{\circ}

x \approx 17.382

Triangle 3 - m\angle A = 49^{\circ}, opposite leg = 12

\sin 49^{\circ} = \frac{12}{x}

x = \frac{12}{\sin 49^{\circ}}

x \approx 15.900
