Answer:

2A /h = b

Step-by-step explanation:

A=1/2bh

Multiply each side by 2

2A = 2*1/2bh

2A = bh

Divide each side by h

2A/h = bh/h

2A /h = b

Step-by-step explanation: First, get rid of the fraction by

multiplying both sides of the equation by 2.

That gives us 2A = bh.

Don't be thrown off by the capital A in this problem.

Just treat it like any other variable.

To get b by itself on the right side of the equation, we now simply

divide both side of the equation by h and our answer is 2A/h = b.

Take a look back at the formula now in the original problem.

Does it look familiar?

It's the formula for the area of a triangle.

Take a look at the image I have provided below.

I have made the "b" purple so you

can see that we are solving for it.

Ab + c = d solve for B
Zepler [3.9K]

Answer:

b = (d-c)/a

Step-by-step explanation:

ab + c = d

We want to solve for b, so we need to get b alone

Subtract c from each side

ab+c-c = d-c

ab = (d-c)

Divide each side by a

ab/a = (d-c)/a

b = (d-c)/a

The hypotenuse of a right triangle is 1m longer than twice one of the other two sides. The third side of the triangle is 15m. Fi
Dimas [21]

Let the length of unknown side be x

So, hypotenuse = 2x + 1

By pythagorean theorem ie , a² = b² + c²

(2x + 1)² = x² + 15²

4x² + 1 + 4x = x² + 225

3x² + 4x -224

(3x +28)(x-8)

x = -9.33 , 8

Since, length can't be negative

x = 8

∴Unknown side length = 8 m

Length of hypotenuse = 2 x 8 + 1 = 17 m

Hope it helps now.

Use the diagram and given information to answer the questions and prove the statement.
Greeley [361]

Answer:

See explanation

Step-by-step explanation:

<u> ASA Postulate (Angle-Side-Angle):</u>

If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.

Consider triangles XYB and ZYA. In these triangles

  • ∠X≅∠Z (given)
  • XY≅ZY (given)
  • ∠Y is common angle

By ASA Postulate, triangles XYB and ZYA are congruent. Congruent triangles have congruent corresponding sides, so

BX≅AZ

Use the function below to find F(3). <br><br> F(x) = 4(1/3)^x​
aalyn [17]

Answer:

4/27

Step-by-step explanation:

F(x) = 4(1/3)^x

Let x =3

F(3) = 4(1/3)^3

Exponents first

F(3) = 4 * 1/27

Then multiply

f(3) = 4/27
