Answer:

<u><em>Note. All numbers are rounded to the nearest tenth</em></u>

1

  • x/9 = cos 48°
  • x = 9 cos 48°
  • x = 6.0

2.

  • x/11 = sin62°
  • x = 11 sin 62°
  • x = 9.7

3.

  • x/8 = tan 75
  • x = 8 tan 75°
  • x = 29.9

4.

  • sin x = 38/53
  • x = arcsin 38.53
  • x = 45.8°

5.

  • tan x = 15/20
  • x = arctan 15/20
  • x = 36.9°

6.

  • cos x = 27/29

Find four consecutive multiples of 3 such that the product of the first, third, and fourth is 1080
Dovator [93]

Answer:

<u>Therefore, we have 6, 9, 12, and 15, that are the first, second, third and fourth consecutive multiples of 3, such the product of 6, 12 and 15 is 1,080.</u>

Step-by-step explanation:

Let's find the factors of 1,080, as follows:

1,080 Dividing by 2 (1,080/2)

540 Dividing by 2 (540/2)

270 Dividing by 2 (270/2)

135 Dividing by 3 (135/3)

45 Dividing by 3 (45/3)

15 Dividing by 3 (15/3)

5 Dividing by 5 (5/5)

1

In consequence, we have:

5 * 3 * 3 * 3 * 2 * 2 * 2

Let's find out what multiples of 3 there are:

5 * 3 = 15 is a multiple of 3,

And 3 * 3 * 2 * 2 * 2 is remaining.

3 * 2 = 6 is also a multiple of 3,

And 3 * 2 * 2 is remaining

3 * 2 * 2 = 12 is also a multiple of 3.

<u>Therefore, we have 6, 9, 12, and 15, that are the first, second, third and fourth consecutive multiples of 3, such the product of 6, 12 and 15 is 1,080.</u>

What is the probability of two dice being rolled and it being less than 7 and divisible by 3
Luden [163]

Answer:

Step-by-step explanation:

(1, 1) <u>(1, 2)</u> (1, 3) (1, 4) <u>(1, 5)</u> (1, 6)

<u>(2, 1)</u> (2, 2) (2, 3)<u> (2, 4)</u> (2, 5) (2, 6)

(3, 1) (3, 2) <u>(3, 3)</u><u> </u>(3, 4) (3, 5) <u>(3, 6) </u>

(4, 1) <u>(4, 2</u>) (4, 3) (4, 4)<u> (4, 5) </u>(4, 6)

<u>(5, 1)</u> (5, 2) (5, 3) <u>(5, 4)</u> (5, 5) (5, 6)

(6, 1) (6, 2) <u>(6, 3) </u>(6, 4) (6, 5) <u>(6, 6) </u>

The bold numbers are less than 7, and the <u>underlined numbers</u> are <u>divisible by 3</u>. The total number of numbers are 36.

The number of numbers that are <u>both</u> <u>underlined</u> and bold are 7.

The probability is 7/36.

(02.07)Which relationship is always true for the angles x, y, and z of triangle ABC? A triangle is shown with a leg extending pa
zysi [14]
Check out the attached image. I drew what I think your book is showing. The figure on the left is triangle ABC without any extended segments. The figure on the right has segment AB extended shown in red. This forms the exterior angle x

The rule that connects x, y and z together is the remote interior angle theorem. It says that adding two interior angles is going to be equal to the exterior angle that is not touching either interior angle. The "remote" part means "far away" so just think of the two angles that are furthest way or not touching the exterior angle in question. 

In terms of algebra, the rule is
x+y = z
