Answer:
The measure of angles of the triangle are 32,32 and 116.
Step-by-step explanation:
It is given that the triangle is an isosceles obtuse triangle with one angle that is 32 degrees.
An angle whose measure is more than 90 degree is called obtuse angle.
It means measure of one angle is more than 90 degree and two tangle are same acute angles.
Measure of one angle is given which is an acute angle (less than 90 degree).
Therefore the measure second angle is als 32.
According to angle sum property the sum all three angle of a triangle is 180 degree.
Therefore the measure of third angle is 116 degree.
To use Law of Sine and Cosine, we need at least one side. Since no side given, therefore we can not find the sides.
Answer: There are 2 batteries which he can buy with his earnings .
Step-by-step explanation:
Since we have given that
Selling price of cans at the recycling center = $0.40 per pound
Number of pounds of cans he sold on Monday = 16.2
Number of pounds of cans he sold on Tuesday = 11.8
Total earning of Samuel is given by
Now, cost of battery =$5.60
So, number of batteries he can buy is given by
So, there are 2 batteries which he can buy with his earnings .
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:
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:
Ahora, el ancho del río es:
Por lo tanto, el ancho del río es 59.9 metros.
