DTBC is a rhombus

<RTB = <FCB

Find

RD = DF

Solution

  • <RTB = <FCB             Given
  • TD = DC                     Property of a Rhombus (all four sides are equal)
  • <RDT = <FDC             Vertically opposite angles are equal
  • ΔRDT ≅ ΔFDC           Δ = triangle. The Δs are congruent by ASA.
  • RD = DF                      Parts of congruent triangles are congruent.

You will get problems like the way you were trying to do it. But you should just mark out what you know. I think that you might have forgotten about vertically opposite angles.

The length of a rectangle is 1 ft less than double the width, and the area of the rectangle is 21 ft^2. Find the dimensions of t
ICE Princess25 [194]

Let the width be w, then length = 2w - 1

Area = length times width = w(2w - 1) = 21.

Thus, 2w^2 - w = 21 or 2w^2 - w - 21 = 0

Solving the quadratic equation gives that w = 3.5.

Therefore, width is 3.5 ft and length is 2(3.5) - 1 = 6 ft.

She is not correct, because $3.00 divided by 6 is 50 cents, so by using that equation she could evaluate that she is wrong and find the correct answer.

Pamela is 6 years younger than Jiri. The sum of their ages is 78 . What is Jiri's age?
Alona [7]
Let’s make

P = Pamela
J = Jiri

J - 6 = P

P + J = 78

We can replace P with J - 6 because they are the same thing.

J - 6 + J = 78

2J - 6 = 78

2J = 84

J = 42

Jiri is 42 years old.
