Answer:

$x = -\dfrac{5}{3c}$

Step-by-step explanation:

You want x alone on the left side.

x is being multiplied by 3 and by c.

The opposite operation of multiplication is division. You must divide 3xc by 3c to end up with just x.

You must do the same operation to both sides of an equation, so divide both sides by 3c.

$3xc = -5$

Divide both sides by 3c.

$\dfrac{3xc}{3c} = \dfrac{-5}{3c}$

Simplify both sides.

$x = -\dfrac{5}{3c}$

Answer:

140°

Step-by-step explanation:

Angles 1 and 3 are "corresponding" angles, so are congruent.

∠1 = ∠3

20x +60 = 30x +20

40 = 10x . . . . . . . . . . . . subtract 20x+20

4 = x . . . . . . . . . . . . . . divide by 10

∠1 = 20x +60 = 20(4) +60 = 80 +60

∠1 = 140°

A rhombus is cut along the diagonals to make four triangles. Which three statements are correct for any rhombus? 1) All four tri

Nikolay [14]

Answer:

1). All four triangles are right-angled.

3.) All four triangles are congruent.

4) Area of a rhombus = 4 x area of one triangle.

Step-by-step explanation:

If a rhombus is cut into four triangles using diagonals, the three statements that would apply to any rhombus would be that 'all those four triangles would be right-angled,' 'the triangles would be congruent to one another,' and 'area of one triangle * 4 would be equal to the area of the rhombus.'

As we know, the diagonals bisect one another in a rhombus at 90° and the angles opposite to one another are equal. This proves that all four triangles constructed through the diagonals would be ≅ through SSS congruency and perpendicular to one another because the corresponding edges of the congruent triangles are also ≅ . Since the rhombus is divided into four equal parts, the area of one triangle into four would be equals to the area of the rhombus. Thus, options 1, 3, and 4 are the correct answers.
