Answer:

h = 3\sqrt{3}

c = 4\sqrt{2}

Step-by-step explanation:

✔️Finding h using trigonometric ratio:

Reference angle = 60°

Opposite = h

Adjacent = 3

Thus:

tan(60) = \frac{h}{3}

\sqrt{3} = \frac{h}{3} (tan 60 = √3)

Multiply both sides by 3

3\sqrt{3} = h

h = 3\sqrt{3}

✔️Finding c using trigonometric ratio:

Reference angle = 45°

Hypotenuse = 8

Adjacent = c

Thus:

cos(45) = \frac{c}{8}

\frac{\sqrt{2}}{2} = \frac{c}{8} (cos 45 = √2/2)

Multiply both sides by 8

\frac{\sqrt{2}}{2} \times 8 = c

\sqrt{2} \times 4 = c

c = 4\sqrt{2}
