usa el teorema de la altura para proponer como se podria construir un segmento cuya longitud sea media proporcional entre dos se
Mrac [35]
Usando el teorema de altura 

El teorema de altura relaciona la altura (h) de un triángulo rectángulo (ver figura) y los catetos de dos triángulos que son semejantes al anterior ABC, al trazar la altura (h) sobre la hipotenusa. De manera que e<span>n todo </span>triángulo rectángulo, la altura (h<span>) relativa a la </span>hipotenusa<span> es la </span>media geométrica<span> de las dos proyecciones de los </span>catetos<span> sobre la </span>hipotenusa<span> (</span>n<span> y </span>m<span>). Es decir, se cumple que:

</span>\frac{n}{h}= \frac{h}{m}

Dado que el problema establece <span>construir un segmento cuya longitud sea media proporcional entre dos segmentos de 4 y 9 cm, entonces, digamos que n = 4cm y m = 9cm tenmos que:

</span>\frac{4}{h}= \frac{h}{9}

De donde:

h= \sqrt{(4)(9)}=\sqrt{36}=6cm

¿Cómo se podria construir si los segmentos son de a cm y b cm?

Si los segmentos son de a y b cm entonces a y b son parámetros que pueden tomar cualquier valor positivo siempre que se cumpla que:

h= \sqrt{ab}

In ΔABC shown below, if BG = 38 what is DG?<br><br> A) 19<br><br> B) 57<br><br> C) 38<br><br> D)17
Mekhanik [1.2K]

Answer:

Basically G is centeroid (intersection point all three medians) so it divides BD in the ratio of 2:1

if bd is x then 2x/3 = BG i.e 38

so GD is x/3 i.e 19

Janice correctly answered 21 of the 24 question. What percent of the questions did she answer correctly?
ikadub [295]
Answer: 87.5%

Explanation: Since Janice answered correctly 21 questions out of 24 questions, you would divide 21 from 24

21/24 = 0.875

0.875 as a percentage would mean moving the decimal point two places to the right as 87.5%
