Exact Form:
21/64
Decimal Form:
0.328125
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:
5" by 6"
Step-by-step explanation:
Just multiply each of the dimensions 15" and 18" by 1/3:
5" and 6"
The poster, 1/3 of the original size, will have dimensions 5" by 6".
The answer is 16 cakes
3/4= .75
.75/1=12/x
x=16
Hope this helps :)
