Answer:

x=20

Step-by-step explanation:

The lines are parallel so those two angles are the same.

Therefore:

2x = x + 20

2x-x = x + 20 -x

x=20

Answer:

221.87 feet

Step-by-step explanation:

Given that,

A 525 ft cable runs from the top of an antenna to the ground.

The angle of elevation made by the ground to the top of an antena 25°

We need to find the height of the antenna.

Using trigonometry,

Hypotenuse, H = 525 ft

θ = 25°

So,

$\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft$

So, the height of the antenna is equal to 221.87 feet.

A rectangle has a perimeter of 20 cm. Its longest side is 6 cm. What is its area?

melamori03 [73]

Answer:

$\boxed {24 cm^{2}}$

Step-by-step explanation:

Finding the smaller side :

⇒ P = 2(l + w)

⇒ 20 = 2(6 + w)

⇒ 6 + w = 10

⇒ w = 4 cm

Finding area :

⇒ 6 × 4

⇒ 24 cm²
