The angle measurements the carpenter needs to cut the carpet to make it fit in his room are 144°, 144°, 144°, 144°, 144°, 90°, and 90°

<h3>Angles in a polygon</h3>

From the question, we are to determine the angle measurements that the carpenter needs to cut the carpet to make it fit in his room

The diagram shows a heptagon with two of its angles, a right-angle each, and the remaining angles have equal values, x.

First, we will calculate the sum of angles in a heptagon

The sum of angles in a polygon is given by the formula

Sum of angles in a polygon = (n-2)180°

Where n is the number of sides

For a heptagon, n = 7

∴ Sum of angles in a heptagon = (7-2)180°

= 5×180°

= 900°

Now, considering the given diagram, we can write that

x + x + x + x + x + 90° + 90° = 900°

5x + 180° = 900°

5x = 900° - 180°

5x = 720°

x = 720°/5

x = 144°

Hence, the angle measurements the carpenter needs to cut the carpet to make it fit in his room are 144°, 144°, 144°, 144°, 144°, 90°, and 90°

Make x the subject<br>thank you

Answer:

$x =\sqrt{\frac{a^6m}{b^2}+n}$

General Formulas and Concepts:

Order of Operations: BPEMDAS
Equality Properties
Exponent Power Rule: $(b^m)^n=b^{mn}$

Step-by-step explanation:

<u>Step 1: Define equation</u>

$a\sqrt{\frac{x^2-n}{m} } =\frac{a^2}{b}$

<u>Step 2: Solve for </u><em><u>x</u></em>

Multiply <em>a</em> on both sides: $\sqrt{\frac{x^2-n}{m} } =\frac{a^3}{b}$
Square both sides: $\frac{x^2-n}{m} =(\frac{a^3}{b})^2$
Simplify: $\frac{x^2-n}{m} =\frac{a^6}{b^2}$
Multiply <em>m</em> on both sides: $x^2-n =\frac{a^6}{b^2}m$
Add <em>n</em> to both sides: $x^2 =\frac{a^6}{b^2}m+n$
Simplify: $x^2 =\frac{a^6m}{b^2}+n$
Square root both sides: $x =\sqrt{\frac{a^6m}{b^2}+n}$

Solve the system by elimination.<br> -6x + y = 0<br> 9x - 8y = 4

mixas84 [53]

Answer:

(4, 4 )

Step-by-step explanation:

Given the 2 equations

- 6x + 6y = 0 → (1)

9x - 8y = 4 → (2)

Multiplying (1) by 3 and (2) by 2 and adding will eliminate the x- term, that is

- 18x + 18y = 0 → (3)

18x - 16y = 8 → (4)

Add (3) and (4) term by term to eliminate x, then

2y = 8 ( divide both sides by 2 )

y = 4

substitute y = 4 into either of the 2 equations and solve for x

Substituting into (2)

9x - 8(4) = 4

9x - 32 = 4 ( add 32 to both sides )

9x = 36 ( divide both sides by 9 )

x = 4

Solution is (4, 4 )
