X=51
Add 57 and 61 and subtract from 180 (straight lines and 180 degrees)

That's y which is 62 and add the 67 degrees.

And once again subtract from 180 (degree fed of a triangle) to find x

What is the area of the model in the problem?

nata0808 [166]

Answer:

$A=x^2+12x+27\ units^2$

Step-by-step explanation:

we know that

The area of the model is equal to the area of a rectangle

The area of a rectangle is equal to

$A=LW$

we have

$L=x+9\ units$

$W=x+3\ units$

substitute

$A=(x+9)(x+3)$

Apply distributive property

$A=x^2+3x+9x+27$

Combine like terms

$A=x^2+12x+27\ units^2$

kolezko [41]

3x + 1 = 2x + 6
subtract 2x from both sides

x + 1 = 6
subtract 1 from both sides

x = 5

Bonjour est que quelqu'un pourrait m'aider svp pour cette exercice des mathématique Merci

(Le français n'est pas ma langue maternelle, alors je m'excuse d'avance si quelque chose n'est pas clair!)

Il me semble que le triangle MNP devrait ressembler à celui que j’ai attaché.

Les triangles MNP et MQR sont similaires, les côtés correspondants sont donc proportionnels:

$\dfrac{MQ}{MN}=\dfrac{MR}{MP}=\dfrac{QR}{NP}$

$\implies\dfrac{2,5}6=\dfrac{MR}{5,7}=\dfrac{1,9}{NP}$

$\dfrac{2,5}6=\dfrac{MR}{5,7}\implies MR=2,375$

$\dfrac{2,5}6=\dfrac{1,9}{NP}\implies NP=4,56$
