Find the area of the rhombus.<br> A=<br> square units
Olin [163]
The answer should be 24 square units.

5 is the hypotenuse and the one we need is the base and the height. They gave us the height, which was 6 in total but 3 for the triangle. But we needed to find the base.

In order to do that, we need to use the Pythagorean Theorem.

a^2+b^2=c^2

3^2+b^2=5^2

9+b^2=25

Subtract 9 from both sides

b^2=16

Then square root both sides.

b=4.

Now that we have the base, you can then find the area of the triangle.

BH/2
4*3/2
12/2
6

So one triangle equals to 6. Then multiply that by 4 to find the area of the rhombus. Which would be 24 square units.

Solve algebra 2 bju press
Nitella [24]

Remark

It looks like all you want is question 6. If that is the case, there are two ways to do it.

Algebra

<u>First answer</u>

abs(b - 22) = 5      Equate to + 5

b - 22 = 5              Add 22 to both sides.

b = 5 + 22

b = 27

<u>Second Answer</u>

Equate to - 5

b - 22 = -5

b = 22 - 5

b = 17

Method Two

<u>Graph the question</u>

The graph y = abs(b - 22) is shown below in red.

The values of y when y =5 are shown in blue.

a regular polygon has a perimeter of 36 inches. each side is exactly 6 inches long. which figure does this discribe?
fgiga [73]
Since a side is only 6 inches long and the total perimeter is 36; take 36/6 and you get 6. The only figure with six sides is a hexagon, thus your answer is hexagon.
