Ejercicio 1 Halle los valores de los ángulos A y B

Ejercicio 2
Halle los valores de los ángulos D y E

Ejercicio 3
Considere al triángulo ABC equilátero y halle los valores de y y x

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

yes, whats the problem?
