Visualize line AB extending past point A (like it does at point B)

You'll see that 180 ( line AB ) minus 129 is 51

Angle 51 is vertical to the other angle inside the triangle that is unnamed.

Now you have 2 angles.

180-45-51=84

The total length of the steel used in the frame is 270 cm, if the decorative steel up of 6 stems and each stem is 45 cm.

Step-by-step explanation:

The given is,

Decorative steel made from circular circle of 6 stems

The length of the stem is 45 cm

Step:1

We need to find the total length of the steel used in the decorative steel,

Let, T - Total length of the steel

L - Length of the stem

n - Number of stems used in steel frame

Step:2

Formula to find the total length of the steel is,

$T=$ $l$ × $n$

From given,

$l$ = 45 cm

$n$ = 6 stems

Substitute the values in formula,

$T =$ ( 45 × 6 )

= 270

$T =$ 270 cm

Result:

The total length of the steel used in the frame is 270 cm.

If every dimension of a two-dimensional figure is multiplied by k, by what quantity is the area multiplied?

Igoryamba

For example: Square has dimension a
A = a² and if every dimension is multiplied by k new dimension would be:
A 1 = k² a² = k² A.
Or the area of rhombus: A = d1 * d 2 / 2
New area is: A 1 = k d 1 * k d 2 / 2 = k² A
Answer: If every dimension of two-dimensional figure is multiplied by k, the area is multiplied by k².

Damm [24]

Answer:

{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }

Step-by-step explanation:

As per the definition, a natural number is a counting number (non-fractional number) that is greater than zero, but not equal to zero.

A set of natural numbers below 12 (but not including 12, because such isn't specified) would henceforth be;

{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }
