Answer:
5/12
Step-by-step explanation:
change 1 1/4 to improper fraction:
1 1/4=5/4
find common denominator: 12
5/4=15/12
5/6=10/12
subtract:
15/12-10/12=5/12
hopefully this helps :)
20 square yards. 15 * 12 is 180 and then you divide it by 9 which gives you 20 square yards. 9 square feet are equivalent to a square yard.

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:
J and K are supplementary
Step-by-step explanation:
Given
The attached image
Required
The true statement
From the attached image, it is hard to determine the values of angles I and L as there are no enough information to determine their values.
However, J and K can be worked easily.
From the image
--- vertically opposite angles
And:
---- angle on a straight line
Substitute:
When two angles add up to 180, the angles are supplementary.
<em>Hence, (c) is correct</em>
