I'm on a phone right now so I may mess up.

In this question you have to take advantage of corresponding parts. You can find the angle beside the 65 degree angle by doing 180-65=115. Using your understanding of corresponding parts you can now conclude that 55+x=115. Now you just do the algebra and you get x=60

se tiene que embaldosar el patio interior de un edificio con baldosas cuadradas de 30 cm de lado. El patio es rectangular y sus

shepuryov [24]

Answer:

40,000 baldosas

Step-by-step explanation:

Lo primero que debemos hacer aquí es calcular el área del patio rectangular.

El mejor enfoque para esto es convertir primero sus medidas a centímetros

Matemáticamente, 100 cm = 1 m, entonces 10 m se convierten en 1000 cm y 12 m se convierten en 1200 m.

El área de un rectángulo es L * B y, por lo tanto, tenemos 1200 * 1000 = 1,200,000 cm ^ 2

Ahora, para saber la cantidad de azulejos que tendrá el patio, necesitaremos dividir el área del patio por el área de los azulejos

Matemáticamente, eso sería 1,200,000 / 30 = 40,000 fichas

Answer:

The perimeter of triangle is 30ft.

Step-by-step explanation:

First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :

${a}^{2} + {b}^{2} = {c}^{2}$

${a}^{2} = {c}^{2} - {b}^{2}$

$a = \sqrt{ {c}^{2} - {b}^{2} }$

Let b = 12,

Let c = 13,

$a = \sqrt{ {13}^{2} - 12 {?}^{2} }$

$a = \sqrt{25}$

$a = 5feet$

Next you have to find the perimeter of triangle by adding all the sides together :

$perimeter = 5 + 12 + 13$

$perimeter = 30feet$
