Using trigonometric ratio, the length of the ladder that reached the window is 20.03 feet
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let l represent the length of the ladder, using trigonometric ratio:
sin(64) = 18/l
l = 20.03 feet

Answer:
The approximate elevation of the "ojos del salado" volcano is 19,686 feet above sea level
Step-by-step explanation:
Let
y -----> elevation of the "ojos del salado" volcano
x -----> elevation of the "khangar" volcano
we know that
The elevation of the "ojos del salado" volcano is about 3 times as great as the khangar volcano
so
----> equation A
we have
substitute the value of x in the equation A
therefore
The approximate elevation of the "ojos del salado" volcano is 19,686 feet above sea level
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
a = b and c ≠0, then a c = a c . Another example Consider the equation 12 = 12. Divide both sides by 4.
