Given MO is perpendicular to NP and NO is congruent to PO prove MN is congruent to MP

VladimirAG [237]

Lets imagine the shape
M
/\
/ | \
/ | \
/ | \
P /___ |___\ N
O
Now in If we take â†MOP and â†MON
As MO âŠĄ NP so â MON=â MOP
NO=NP (given)
And MO is a common side
so by side angle side rule of congruency
â†MOP and â†MON are congruent
so MP is congruent to MN

Can you help me plz with 1,2,3,5,6 I'm not in this grade so plz help me

Elina [12.6K]

It looks like for all of these we will be using the Pythagorean theorem.

If you don't know what this is or how to apply it, go to the website "Khan Academy" and watch his video(s) on it. I would suggest going to that site whenever you don't understand something in math :)

I'll just be giving you the answers and won't explain what I'm doing, but please do go to Khan Academy to find out how to do it on your own!!

Anyway, onto the answers.

1) a = 12.5, b = 5.7, c = 13.7.
2) 24
3) 19.2
4) 6.4
5) 18.7
6) 98.5
7) 1.9

Hope this helps!!!

Una torre de 28.2 m de altura esta situada a la orilla de un rio, desde lo alto del edificio el ángulo de depresión a la orilla

Svet_ta [14]

Answer:

El ancho del río es 59.9 metros.

Step-by-step explanation:

El ancho del río lo podemos calcular con la siguiente relación trigonométrica asumiendo que la torre forma un triángulo rectángulo con el río:

$tan(\theta) = \frac{CO}{CA}$

En donde:

CA: es el cateto adyacente = Altura de la torre = 28.2 m

CO: es el cateto opuesto = ancho del río =?

θ: es el ángulo adyacente a CA

Dado que el ángulo de depresión (25.2°) está ubicado fuera de la parte superior de la hipotenusa del triángulo que forma la torre con la orilla opuesta del río, debemos calcular el ángulo interno (θ) como sigue:

$\theta = (90 - 25.2)^{\circ} = 64.8 ^{\circ}$

Ahora, el ancho del río es:

$CO = tan(\alpha)*CA = tan(64.8)*28.2 = 59.9 m$

Por lo tanto, el ancho del río es 59.9 metros.

Espero que te sea de utilidad!
