Answer:
What's the question?
Step-by-step explanation:
The measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees
<h3>Angle of elevation and depression</h3>
These method is used to determine the side and angles of a triangle
From the question given, we have the following parameters
Base of the building = 7feet (Adjacent side)
Height of the building = 18 feet (Opposite side)
Required
angle of elevation of the building
Using the SOH CAH TOA identity
tanФ = opp/adj
tanФ = 18/7
Ф = 68.73 degrees
Hence the measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees

Answer:
65 cubic units
Step-by-step explanation:
Put the numbers in the formula and do the arithmetic.
V = 1/3Bh
V = 1/3(30)(6.5) = 65 . . . cubic units
