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

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

$\sqrt{2} \times 4 = c$

$c = 4\sqrt{2}$

For what value of x is the area of the rectangle greater than the perimeter? The base of the perimeter is x+2

TiliK225 [7]

If we call the area A, then $A=7(x+2)=7x+14$
if we call the perimeter P, then $P=7*2+2(x+2)=2x+18$
$A>P$
$7x+14>2x+18$
subtracting 14 gives $7x>2x+4$
subtracting 2x gives $5x>4$
dividing by 5 gives $x>\frac{4}{5}$
or $x>0.8$

What do the difference between the adjacent angle and opposite angle

PtichkaEL [24]

Answer:

The difference between the adjacent angle and the opposite angle is that for the adjacent side is the side next to the reference angle, and for the opposite side is the side directly across from the reference angle.

Hope this helped!
