The range is the number of units between the smallest and largest number. organising your numbers from smallest to largest:

12, 19, 20, 28, 34, 36, 45, 45

in your case 12 is the smallest number of your set. lowering it to 3 would increase the distance between the two numbers, therefore increasing the range

hope that helps :)

CA=2,AB=3, The angle of C=90 degrees what is the angle of B?

Levart [38]

Answer:

m∠B ≈ 41.81°

Step-by-step explanation:

If we draw a picture, it would help a lot. Once we visualize the triangle, we can see that we have sin∅ = 2/3. So, plugging into your calc,

sin∅ = 2/3

∅ = sin^-1(2/3)

∅ = 41.8103

Can you explain how you would convert 4 m to millimeters?

Andrew [12]

M to millimetres is 3 steps. m > dm > cm > mm. since it is 3 steps down, the comma goes 3 places left. 4 > 0,4 > 0,04 > 0,004. so 4 m is equal to 0,004 mm

According to this diagram what is tan 62

kicyunya [14]

The figure is not attached. So, I have attached it from the link- brainly.com/question/4198293

Answer:

$\tan(62)=1.875$

Step-by-step explanation:

Label the triangle ABC as shown below.

Given:

AB = 8, BC = 15, AC = 17, m∠ABC = 90°, m∠ACB = 28°, m∠BAC = 62°

The tangent of a given angle is given as the ratio of the opposite side and the adjacent side. The opposite side is the side opposite to the angle. The adjacent side is the other leg of the right angled triangle.

Here, the opposite side to angle A is BC and adjacent side is AB.

Therefore, the tan ratio of angle A is given as:

$\tan A=\frac{BC}{AB}\\\tan (62)=\frac{15}{8}=1.875$

Hence, tan 62 = 1.875.
