<h3><u>Answer:</u></h3>
  • The value of x is 17.
<h3><u>Step-by-step explanation:</u></h3>

<u>We know that the lines are parallel because it is given that:</u>

  • a ∥ b

<u>Now, let's form an equation.</u>

  • => 2x + 5 + 8x + 5 = 180

<u>Let's solve!</u>

  • => 10x + 10 = 180
  • => 10x = 170
  • => x = 17

Hence, the value of x is 17.

What is the area of a 120 degree sector of a circle with the radius of 15 cm? Round to the nearest square cm.
Delvig [45]

Answer:

236 cm^2

Step-by-step explanation:

Formula

Area = sector angle/360 * pi * r^2

Givens

Sector angle = 120

r = 15

Solution

Area = 120/360  * 3.14 * 15 * 15

Area = 1/3 * 3.14 * 225

Area = 235.5

Area = 236 cm^2

Answer: 2748.5 feet

Step-by-step explanation:

Given that the

Height h = 120 feet.

angle of depression = 2.5 degrees

The angle of depression is equal to the angle of elevation.

The base of the observation deck will be achieved by using trigonometry ratio.

Tan Ø = opposite/ adjacent

Opposite = height = 120 feet

Adjacent = base = ?

Substitutes the given parameters into the trigonometry ratio.

Tan 2.5 = 120 / adjacent

Adjacent = 120 / tan 2.5

Adjacent = 2748.452

Therefore, the base of the observation deck is 2748.5 feet

6. Interest is compounded semianually. Find the amount in the account after the given time.
patriot [66]

The amount in the account after the given time if compounded semiannually is $1104.2

<h3>Compound interest </h3>

Interest is any amount added on a sum of money over a period of time. The formula for calculating the compound interest is:

A = P(1+r/n)^nt

Given

P = $1000

rate r = 0.05

time =3years

n = 2

Substitute

A = 1000(1 + 0.05/3)^3(2)
A= 1000(1.1042)
A = $1104.2

Hence the amount in the account after the given time if compounded semianually is $1104.2
