Answer:
The altitude will begin at angle D and go in a straight line downwards.
The perpendicular bisector will be a straight line going from one corner to the other corner, not directly downwards.
Please help. You don't have to explain the answer. :)

Answer:
1). a = 9.42 m
2). b = 6.37 m
3). c = 4.48 m
Step-by-step explanation:
In the figure attached,
By applying tangent rule in triangle ADE,
tan47 =
c =
c =
c = 4.476
c ≈ 4.48 m
Now we apply the same rule in triangle ACE,
tan37° =
b =
b =
b = 6.37 m
Now apply the tangent in triangle ABE,
tan27° =
a =
a =
a = 9.42 m
Suppose first that is a normal subgroup. Then by definition we must have for all

Answer:
The transformation of to
consists in a vertical translation. The new equation is
.
Step-by-step explanation:
Let . We proceed to make the required transformations on
, which consists in one vertical translation, 3 units in the -y direction. That is to say:
(1)
Then, the transformation of to
consists in a vertical translation. The new equation is
.
