3 0

Answer: x = (-n/2)

Step-by-step explanation:

-3(x+n)=x      Problem:

-3x-n=x         Distributive property

-n=2x            Add 3x to both sides

2x=-n            Switch equation around to make it easier to look at

x= -n/2          Divide by 2 on each side

The formula for the area of a rhombus is A = a equals StartFraction one-half EndFraction d 1 d 2.d1d2, where d1 and d2 are the l
AlexFokin [52]

The two equivalent equations are d₁= 2a/d₂ and d₂= 2a/d₁ , Option 2 and 5 is the right answer.

<h3>What is a Rhombus ?</h3>

Rhombus is a quadrilateral with all the sides equal to each other.

It is given that d₁ and d₂ are the lengths of the diagonals.

and Area = a

a = (1/2) d₁ * d₂

  • 2a = d₁ * d₂

       d₁ * d₂ = 2a

       It can be written as

        d₁= 2a/d₂

a = (1/2) d₁ * d₂

  • d₁ * d₂ = 2a

        d₂= 2a/d₁

Therefore Option 2 and 5 are the correct answer.

The options of this question are:

1.  d₁=2Ad₂

2. d₁= 2A/d₂

3. d₂= d₁/2A

4. d₁= 2A/d₂

5. d₂= 2A/d₁

two horizontal lines are cut by a transversal. what is the least number of angle measures you need to know in order to find the
jeka94

Answer: The answer is only one angle. Explained.

Step-by-step explanation: As given in the question and shown in the attached figure, the lines horizontal lines 'p' and 'q' are cut by the transversal 'r'. We need to determine the least number of angles among the eight angles mentioned in the figure to find the measure of all the angles.

Suppose, the measure of ∠1 is given as x°.

So, ∠2 = 180° - x (linear pair of angles),

∠3 = x (=∠1, vertically opposite angles),

∠4 = 180° - x (=∠2, verticaly opposite angles),

∠1 = ∠5, ∠2 = ∠6, ∠3 = ∠7, ∠4 = ∠8. These are pairs of correspomding angles.

Thus, we need the measure of only one angle to find the measure of all the angles.

Hence explained.
