Use the Pythagorean theorem and the following diagram to help you find the area and perimeter of the following triangle. Please

Mekhanik [1.2K]

Answer:

Perimeter = 30

Area = 30

Step-by-step explanation:

$(x+8)^2 -x^2 = 12^2$

$x^2 +16x +64 - x^2 = 144$

$16x+64=144$

$16x = 80$

$x = 5$

Double check:

$\sqrt{12^2 + 5^2} = (5+8)\\\sqrt{12^2 + 5^2} = 13\\13 = 13$

Perimeter:

$12+5+13=30$

Area( $\frac{1}{2}bh$ ):

$\frac{1}{2}$ × 12 × 5 = 30

Un submarino se encuentra 50m por debajo del nivel del mar y comienza a subir 2m cada 5 minutos ¿a que profundidad se encuentra

Trava [24]

Answer:

a) El submarino se encuentra a una profundidad de 26 metros una hora después de haber comenzado el ascenso.

b) Al submarino le falta 1 hora y 5 minutos para llegar a la superficie.

Step-by-step explanation:

a) De acuerdo con el enunciado, la cantidad de metros ascendidos por el submarino es directamente proporcional al tiempo, entonces la profundidad del submarino a la hora de haber comenzado el ascenso se obtiene mediante la siguiente relación lineal:

$h = 50\,m - \frac{2\,m}{5\,min}\times 60\,min$
