Task no. 2: another solution is 45* (4/5) / (6/4) = 24 min.
Answer:
About 5.5, but it is technically closer to 5.6 so I am not entirely sure
Step-by-step explanation:
Since EB and DC are parallel, triangles ABE and ACD are similar by AA. Therefore:

Hope this helps!
Answer: X = 9
Show Your Work:
All Angles & Sides = 60.
All Triangles = 180.
60 x 3 = 180.
Angle N:
7x - 3 = 60
7 * 9 - 3 = 60.
Step-by-step explanation:
y = kx, where k is the constant of proportionality. (1)
Therefore y = x and line B depicts that.
For this question, we need the formula τ = F x d<span>, and just plug the numbers in.
</span>
Given the formula <span>τ = F x d</span>
Where τ = torque,
F = force applied, &
d = distance from the axis / hinge,
<span>τ = 300 c 0.8 = 240Nm</span>
Disregard the weight of the door or if there's any friction at the hinge. None of this will change the torque applied.
