Answer:
17. h = l − l cos θ
18. 1.40 m
Explanation:
Let's call d the height of the triangle. We can then say:
h = l − d
Using trig, we can write d in terms of l and θ:
d = l cos θ
h = l − l cos θ
If l = 6 m and l cos θ = 40°:
h = 6 − 6 cos 40
h ≈ 1.40

Characteristic properties of a given substance is different from its other properties is that there is no change as to what it is no matter how big or how small the sample of the given substance is. Another thing is that it doesn't affect the chemical nature of the matter. The characteristic properties of a given substance can either be a physical property of the substance or a chemical property of the substance. Either way, there is no change to it even if the size of the substance changes.
