Answer:
<em>Gradient of KL = 2</em>
Step-by-step explanation:
From the diagram, we are to calculate the gradient of KL. Gradient is salso known as the slope of the line.
Gradient of KL = ΔOK/ΔOL
Given
OK = 2OL
Substitute into the formula
From the diagram, ΔOL = -5
ΔOK = 2ΔOL
ΔOK = 2(-5)
ΔOK = -10
Hence;
Gradient = -10/-5
<em>Gradient of KL = 2</em>

Step-by-step explanation:
Each interior angle=140°
(n-2)180°/n=140°
180°n-360°/n=140°
180°n-360°=140°n
180°-140°=360°
40°n=360°
n=360°/40°
n=9
Hence, the number of sides of the polygon is 9.
It is nonagon .
We need to apply trigonometry for easy calculations.
Let Z represent the ramp.
sin x = wall divided by the ramp
Let x = 7°.
sin 7° = 2.5/Z
We now solve for Z.
Z = 2.5 ÷ sin 7°
Z = 20.5137726212
We round off to the nearest tenth of a foot. This means to round off to the ones place.
Z = 21 feet
Done.
