A. 60<br> B. 15<br> C. 120<br> D. 6
Montano1993 [528]

Answer:

C. 120

Step-by-step explanation:

The figure shows that angles BEC and KEC are congruent. Their measures are equal.

m<KEC = m<BEC

10x = 6x + 24

4x = 24

x = 6

m<BEK = 2m<KEC

m<BEK = 2 * 10x

m<BEK = 2 * (10)(6)

m<BEK = 2 * 60

m<BEK = 120

El area de un triangulo es de 432 unidades cuadradas. ¿Cual es la altura y la base sabiendo que la base mide tres veces su altur
Lelu [443]

Usando el concepto del área del triángulo, se encuentra que :

  • La altura es de 16.97 unidades.
  • La base es de 50.91 unidades.

---------------------------

El área del triángulo de base b y altura h es dada por:

A = \frac{bh}{2}

---------------------------

  • El area es de <u>432 unidades quadradas</u>, o sea, A = 432
  • La base mide <u>tres veces su altura</u>, o sea, b = 3h

---------------------------

<u>Reemplazando en la ecuación para el área</u>, es posible encontrar la altura:

A = \frac{bh}{2}

432 = \frac{3h \times h}{2}

3h^2 = 864

h^2 = \frac{864}{3}

h^2 = 288

h = \sqrt{288}

h = 16.97

La altura es de 16.97 unidades.

---------------------------

La base es dada <u>en funcion da altura,</u> o sea:

b = 3h = 3(16.97) = 50.91

La base es de 50.91 unidades.
