The ladder and the wall it leans on are illustrations of right triangle
The horizontal distance from the base of the ladder is 5.41 feet
<h3>How to determine the horizontal distance?</h3>
The given parameters are:
Length (L) = 26 feet
Angle of elevation (θ) = 78 degrees
The horizontal distance (D) is calculated using the following cosine ratio
cos(θ) = D/L
Substitute known values
cos(78) = D/26
Make D the subject
D = 26 * cos(78)
Multiply
D = 5.41
Hence, the horizontal distance from the base of the ladder is 5.41 feet

Answer:
(x,y)=(5-2y,y), y belongs to all real numbers
Step-by-step explanation:
x=5-2y
3x=15-6y
3(5-2y)=15-6y
15-6y=15-6y
y∈All Real Numbers
(x,y)=(5-2y,y), y∈All Real Numbers
Answer:
this y easy use your mind
Add together the values to get the total cost
Then divide the discount by the total cost to find the percentage
