Answer:
La torre tiene 543.78 pies de altura.
Step-by-step explanation:
Podemos pensar en esta situación como si fuera un triángulo rectángulo, donde el cable es la hipotenusa y la torre es uno de los catetos. (Abajo se puede ver un dibujo de esta situación).
Nosotros queremos encontrar el valor de H, que es el cateto opuesto al ángulo conocido de 65°.
Entonces simplemente podemos usar la relación:
Sin(θ) = (cateto opuesto)/(hipotenusa)
donde:
cateto opuesto = H
θ = 65°
hipotenusa = 600 ft
sin(65°) = H/600ft
sin(65°)*600ft = H = 543.78 ft
La torre tiene 543.78 pies de altura.

Answer: she invested $2500 at the rate of 10%.
she invested $1500 at the rate of 6%.
Step-by-step explanation:
Lisa invests $x in bond A and $y in bond B.
Lisa invests $4,000 in two types of bonds, bond A and bond B. This means that
x + y = 4000
Bond A offers a 10% return, and bond B offers a 6% return. Therefore,
Interest on bond A is 0.1x
Interest on bond B is 0.06y
Her total return on the investment is $340. It means that
0.1x + 0.06y = 340
Therefore, The system of linear equations defining the situation is
x + y = 4000
0.1x + 0.06y = 340 - - - - - - - - - - -1
Substituting x = 4000 - y into equation 1, it becomes
0.1(4000 - y) + 0.06y = 340
400 - 0.1y + 0.06y = 340
- 0.1y + 0.06y = 340 - 400
- 0.04y = - 60
y = - 60/ - 0.04
y = 1500
x = 4000 - 1500
x = 2500
