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

Answer:
The voltage operating is the 85,20563362
Explanation:
Power is the relation between Voltage and Current so knowing the resistance is going to be constant the equation of power can be just replacing in voltage terms:
1. 
using also Law OHM
2.
Replacing 2 in the equation 1 so all the data are going to be in Voltage terms:
1. 
⇒ 

Ω
So the resistance is constant so the current is going to be the same at the other Power 36 W:
