My question is, “is it over due work or low grades?”
Given:
The length of the ladder = 12 ft
The angle of ladder with ground = 60 degrees
To find:
How far up the building the ladder will reach.
Solution:
Using the given information draw a figure as shown below.
We need to find the vertical distance between the top of ladder and the ground.
Let x be the required distance.
In a right angle triangle,

In the below triangle ABC,



Multiply both sides by 12.


Therefore, the ladder will reach
ft far up the building.
D is your answer
plug in the x value and y value to the equation
when x = 1, and y = 4
-1 + 4 = 3
when x = 5, and y = 8
-5 + 8 = 3
hope this helps :D
