Yes im here ask away. I am doing calculus right now
The height of the building is 19.02 feet, for a 20-ft ladder to lean against the building at an angle of 72 degrees.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Trigonometric ratio is used to show the relationship between the sides and angles of a right angle triangle.
Let h represent the height of the building, hence:
sin(72) = h/20
h = 19.02 feet
The height of the building is 19.02 feet, for a 20-ft ladder to lean against the building at an angle of 72 degrees.

For 30 60 90 triangles, the ratio of the side lengths is
where the first is the shorter leg, the second is the longer leg, and the third is the hypotenuse (the longest side that doesn't form a 90 degree angle)
so the ratio of the longer leg to the hypotenuse is <span>
or
</span>
<span>which equals </span>
