Step-by-step explanation:
If we think about a right triangle, we get that the hypotenuse is 24ft or the length of the ladder. The base of the ladder is 15ft away from the building which is the leg of the right triangle. The screenshot is the diagram (my drawing isn't that good lol:))
Thus we can use cosine function with the angle between the ladder and the ground since we need to find the angle and we get
and
The angle is 51.3 degrees hope that helps!
7x+y-9=0
move constant to the left by adding its opposite to both sides. the sum of the two =0
