Answer:
5.196 m
Step-by-step explanation:
p = La perpendicular del triángulo es la longitud de la antena.
h = La hipotenusa del triángulo es la longitud del cable conectado a la parte superior del poste = 6 m
= Incline el cable con el suelo =
De las funciones trigonométricas sabemos que
La longitud de la antena es 5.196 m.

Answer: D. Triangle MNO is similar to Triangle GHK
Step-by-step explanation:
We know that the sum of the interior angles of a triangle is 180 degrees.
To identify similar triangles, we must look for triangles what share the same combination of interior angles.
Triangle MNO has has known angles of 79 and 22 degrees, which leaves (180 - 79 - 22) 79 degrees for the unknown angle, so two angles of 79 degrees and one of 22 degrees.
We see that DEF has an angle of 82 degrees... so it's not similar.
Triangle PQR has an angle of 20 degrees... so it's not similar either.
Triangle GHK has two known angles of 79 degrees... we know that the unknown is 22 degrees (because the total needs to be 180).
So, both GHK have 2 angles of 79 degrees and one angle of 22 degrees... they are then similar.
The summary of directions of the parabola is:
a) Squared term is x
Parabola either opens up or down.
Positive coefficient means upward opening and negative coefficient means downward opening
b) Squared term is y
Parabola either opens right or left
Positive coefficient means rightwards opening and negative coefficient means leftwards opening
Since the coefficient is positive with squared x term, the parabola opens upward.
So the answer to this question is option D
