sin^2a + tan^2a sin^2a = tan^2a​

Answer:

2

Step-by-step explanation:

3x + 5x  + 8x = 32

taking x common,

(3 + 5 + 8)x = 32

16x = 32

x = 32 / 16

x = 2

Answer: See below

Explanation:

The ultimate method of solving algebra problems will be trying any operations to isolate x, which then gives the value of x.

Operations include combining like terms, dividing and multiplying terms, and etc.

I would be solving [3x + 5x + 8x = 32] as an example.

Solve:

Given

3x + 5x + 8x = 32

Combine like terms through addition

8x + 8x = 32

16x = 32

Divide 16 on both sides to isolate x

16x / 16 = 32 / 16

Answer:

I believe that the answer is NONE the right angle at B should be enough information to prove that DE is ⊥ to AC

Step-by-step explanation:

By the Side-Angle-Side postulates, the triangles ΔABD and ΔCBD are congruent to each other.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

If two triangles are congruent, then the ratio of the corresponding sides will be ONE.

The line DE is the perpendicular bisector of AC. Then we have

In triangles ΔABD and ΔCBD,

DB = DB (Common side)

∠ABD = ∠CBD = 90°

AB = BC (Bisector length)

By the Side-Angle-Side postulates, the triangles ΔABD and ΔCBD are congruent to each other.

Step-by-step explanation: Similar figures have the same shape, but not necessarily the size. If two figures are similar, then their corresponding angles are congruent so <E ≅ <O because these are the corresponding angles in the similarity statement.

Answer:

the surface of "C" would be a triangle if sliced vertically

Step-by-step explanation:

If  vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism, option C is correct.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

If a vertical slice through a three-dimensional solid produces a two-dimensional shape which is a triangle, it means that the solid has a triangular cross-section.

In other words, the cross-section of the solid that is perpendicular to its base is in the shape of a triangle.

A triangular prism is a solid shape that has a triangular cross-section. If you were to take a vertical slice through the prism, the resulting two-dimensional shape would be a triangle.

Hence, if  vertical slice through a three-dimensional solid produces a two-dimensional shape is triangular prism

Answer:

C. c = 10

Step-by-step explanation:

You have to use the Pythagorean theorem:

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = √100

c = 10

Answer:

c = 10

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

6^2 + 8^2 = c^2

36+64= c^2

100 = c^2

Take the square root of each side

sqrt(100) = sqrt(c^2)

Given, the package of invitations contain [tex]12[/tex] invitations and package of envelopes contain [tex]10[/tex] envelopes.

It is given that, Ronnie bought the fewest number of invitations and envelopes so that there is exactly one envelope per invitation with none left over.

That is,[tex]12x-10y=0[/tex].

When, [tex]x=1[/tex] the value of [tex]y[/tex] becomes [tex]1.2[/tex].

It is not possible, since the number package cannot be in decimals.

This is not possible, since the number package cannot be in decimals.

When, [tex]x=3[/tex] the value of [tex]y[/tex] becomes [tex]3.6[/tex].

This is not possible, since the number package cannot be in decimals.

When, [tex]x=4[/tex] the value of [tex]y[/tex] becomes [tex]4.8[/tex].

Answer:

2,172 adults

Step-by-step explanation:

Let adults = x

children = y

x + y = 5400

9.5x + 6.5y = 41,616

Let's use the elimination method to solve this.

Multiply the top equation by -6.5

(x + y = 5400)-6.5

-6.5x - 6.5y = -35100

This will allow us to eliminate the y and add up the other terms

9.5x + 6.5y = 41,616

-6.5x - 6.5y = -35100

3x = 6516

Divide both sides by the coefficient, 3, to isolate the variable, x

3x/3 = 6516/3

x = 2172

=x^2-5x-24

Simplify:

(x-8) (x+3) =0

x= 8 x= -3

Step-by-step explanation:

Here radical rule is that [tex]\sqrt[n]{x^{m} } = x^{m/n}[/tex]  ;  [tex]x\neq 0[/tex] so
