Answer:

The length of x in #1 is 15.57

Step-by-step explanation:

Let's use #1 as an example to teach show you how to do this. In a right triangle we can solve these using trig. In this particular one, we have the measure adjacent to the angle and we are looking for the one opposite of the angle. So we look at all the trig functions and select the one that uses both of those two terms.

Sinα = Opp/Hyp

Tanα = Opp/Adj

Cosα = Adj/Hyp

As you can see, Tan is the function we are looking for. So we plug in all known information into that equation.

Tanα = Opp/Adj -----> Plug in known values

Tan(60) = x/9 ----->Calculate out the trig function

1.73 = x/9 -----> Multiply by the denominator to solve

15.57 = x

Pls help with number 7,8,9 and 10
ella [17]

The answers to all the subparts of the multiplication problem are shown:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

<h3>What is multiplication?</h3>
  • Multiplying in math is the same as adding equal groups.
  • The number of items in the group grows as we multiply.
  • Parts of a multiplication issue include the product, the two factors, and the product.
  • The factors in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the product is the number 54.

So, multiplication of the numbers:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

(Refer to the images attached below for calculations)

Therefore, the answers to all the subparts of the multiplication problem are shown:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

The perimeter of a rectangle is twice the sum of its length and it’s width . The perimeter is 22 meters and I it’s length is 2 m
lukranit [14]

Answer:

The length of this rectangle is 8m.

Step-by-step explanation:

The problem states that the perimeter of a rectangle is twice the sum of its length and it’s width. So

P = 2*l + 2*w

The problem also states that the perimeter is 22 meters. So:

P = 22

2l + 2w = 22.

Also, it states that I is the length and it is 2 meters more then twice it’s width. So

l = 2w + 2

What’s its length?

P = 22

2l + 2w = 22

2(2w+2) + 2w = 22

4w + 4 + 2w = 22

6w = 22 - 4

6w = 18

w = \frac{18}{6}

w = 3

The width is 3m. The length is in function of the width, so:

l = 2w + 2

l = 2*3 + 2

l = 8m

The length of this rectangle is 8m.
