The length of the support post is 40 ft.
<u>Solution:</u>
Given, the height of the wall is 20 ft; support post forms 30 degree
Refer the attached image
Let us name the triangle as ABC where AB is the wall (opposite side) of 20 ft and is 30 degree () and AC is the length of the post.
To find: The length of the post (AC)
we know the formula, (trigonometric formula)
On substituting the values we get,
The value of sin 30 degree is 0.5
Marcus's elevation would be 35 feet BELOW sea level and as an integer it is written as -35. This is because the term BELOW describe an integer that is UNDER sea level. Sea level is ALWAYS 0, meaning anything BELOW it is negative and anything ABOVE it is positive. Using a vertical number line can also show you how integers correlate to sea level elevations.
