Find the area of following rhombuses. Round your answers to the nearest tenth if<br> necessary.

polet [3.4K]

Answer:

$Area =55.4ft^2$

Step-by-step explanation:

Given

The attached rhombus

Required

The area

First, calculate the length of half the vertical diagonal (x).

Length x is represented as the adjacent to 60 degrees

So, we have:

$\tan(60) = \frac{4\sqrt 3}{x}$

Solve for x

$x = \frac{4\sqrt 3}{\tan(60)}$

$\tan(60) = \sqrt 3$

So:

$x = \frac{4\sqrt 3}{\sqrt 3}$

$x = 4$

At this point, we have established that the rhombus is made up 4 triangles of the following dimensions

$Base = 4\sqrt 3$

$Height = 4$

So, the area of the rhombus is 4 times the area of 1 triangle

$Area = 4 * \frac{1}{2} * Base * Height$

$Area = 4 * \frac{1}{2} * 4\sqrt 3 * 4$

$Area =2 * 4\sqrt 3 * 4$

$Area =55.4ft^2$

Prove the polynomial identity.

Ronch [10]

Answer:

The answer to your question is: 2, 4, 5, 1 , 3

Step-by-step explanation:

The first line is the second

(3x² - 6)² - (3x²)² = 36(1 - x)(1 + 1)

The second line is the forth

9x⁴ - 36x² + 36x² - 9x⁴ = 36(1 - x)(1 + x)

The next line is the fifth

36 - 36x² = 36(1 - x)(1 + x)

The next line is the first

36(1 - x²) = 36(1 - x)(1 + x)

The last line is the third

36(1 - x)(1 + x) = 36(1 - x)(1 + x)

Tems11 [23]

Answer:

50 legs

Step-by-step explanation:

We know that a dog has 4 legs, a cat has 4 legs, a giraffe has 4 legs, a duck has 2 legs, and a chicken has 2 legs. So, we want to calculate $2(4)+4(4)+1(4)+5(4)+1(2)+3(2)$ , right?

Wrong! It's a trick question! The chickens aren't on the floor, so they don't count. So, we really want $2(4)+4(4)+1(4)+5(4)+1(2)$ .

We multiply it out to get $8+16+4+20+2$ .

We add these up to get $50$ .

So, our answer is $\boxed{50}$ legs.
