Answer:

I think...

Triangle 2- the perimeter is 22.

Step-by-step explanation:

For perimeter you add all the sides together.

I think for the larger triangle X=4. Because on the 6 side is 4 on the smaller triangle and the 12 side is 8 on the smaller triangle.

So...

6+12+4= 22.

A goat and a cow together weigh 190 kg 640 g. The weight of the goat is 59 kg 720 g. Find the weight of the cow

AVprozaik [17]

Answer: 130 kg 920 g

Step-by-step explanation:

Given

The weight of the goat is 59 kg 720 g

The combined weight of goat and cow is 190 kg 640 g

Suppose, the weight of the cow is x kg

We know, 1 kg=1000 g

Converting weight into kg

Goat weight

$=59+0.720\\=59.720\ kg$

Total weight

$=190+0.640\\=190.640\ kg$

Then, the cow weight is given by

$\Rightarrow 190.640-59.720\\\Rightarrow 130.920\ kg\ \text{or}\ 130\ kg\ 920\ g$

65 POINTS PLEASE HELP

miskamm [114]

Answer:

= -----------

6(x + 7)

Step-by-step explanation:

3x - 21 x^2 - 49

----------- ÷ -------------

18x - 18 x - 1

3x - 21 x - 1

----------- × -------------

18x - 18 x^2 - 49

Factor the top left:

3x - 21 = 3(x - 7)

Factor the bottom left:

18x - 18 = 18(x - 1)

Factor the new bottom right:

x^2 - 49 = (x + 7)(x - 7)

Multiply and simplify the faction:

3(x - 7) x - 1

----------- × -----------------

18(x - 1) (x + 7)(x - 7)

= -------------

6(x + 7)

Given that m angle G- 81", what is m angle I? A)81" B)89 C)91 D)99

seraphim [82]

Answer:

$\text{D) }99^{\circ}$

Step-by-step explanation:

Define a cyclic quadrilateral by a quadrilateral that is circumscribed by a circle. In this case, since the quadrilateral shown is circumscribed by a circle, it is a cyclic quadrilateral.

A property of all cyclic quadrilaterals is that their opposite angles are supplementary, meaning they add up to 180 degrees. Since $\angle G$ and $\angle I$ are opposite angles in the quadrilateral, they must be supplementary. Therefore, we have the equation:

$\angle G+\angle I=180,\\81^{\circ}+\angle I=180,\\\angle I=180-81=\boxed{99^{\circ}}$
