Answer:
Un excursionista camina por un prado llano, observando una montaña a
lo lejos. Mide que el ángulo de elevación entre el suelo
y la cima de la montaña es de 25 grados. Camina 5 millas y luego
mide el ángulo de elevación nuevamente, ahora es de 40 grados. ¿Qué altura tiene
la montaña?

Answer:
V = 929.7
Step-by-step explanation:
Given the equation:
= 
The integral of the above equation is:
= 
Re-organizing the integrals:
= 
Integrating:
ln(CA) - ln(CA0) = 
Inputting the initial conditions of CA and the values of k and V0:
ln(7) - ln(100) = 
1.946 - 4.605 = -0.00286V
-2.659 = -0.00286V
=> V = 
V = 929.720
Approximating to one decimal place,
V = 929.7
Answer:
X = 18
Y = 9√3
Step-by-step explanation:
use sin equation for right angle triangle
The sine of the angle
= ( the length of the opposite side ÷ the length of the hypotenuse.)
according to this question,
sin 30 = 9 / X
1/2 = 9 / X
X = 18
use cosine to find y
The cosine of the angle
= (the length of the adjacent side ÷ the length of the hypotenuse.)
cos 30 = y/x
√3/2 = y/ 18
y = 9 ✓3
