Hey there!
1.21 repeating as a fraction is 40/33.
Hope this was of help, have a great day :)
answer:
x = 29
y = 29
z = 61
step-by-step explanation:
all angles in a triangle must equal 180 degrees.
we were already given the angle degree of 61 degrees so we must include that in our formula to determine the degree of y.
the line in the middle already gives us two more angles because they both are 90 degrees for being a perfect quarter turn.
so to figure out y,
we must add 61+90 and then subtract the sum of that from 180.
so, 61+90 = 150 and 180-151 = 29
therefore,
we can conclude that y = 29
now, to determine the degrees of x and z we do the same thing.
we already know one angle equals 90 degrees.
180-90 = 90
that concludes that x and z must have a sum of 90.
if we use our choices,
39+61 = 100 (no)
39+29 = 68 (no)
29+61 = 90 (CORRECT)
29+29 = 28 (no)
<em>therefore, x = 29 and z = 61</em>
<em></em>
<em>so, in total :</em>
<em>x = 29</em>
<em>y = 29</em>
<em>z = 61</em>

Answer:
What shapes are you talking about?
Step-by-step explanation:
Answer:
Step-by-step explanation:
Supongo que te refieres a ''despejar'' la variable.
Primero, aisla los terminos independientes en la derecha y los que tienen variables, en la izquierda. En este caso, el 3 es independiente y no está en la derecha. Para poder moverlo, debo hacer la operación contraria. Por ejemplo, está siendo sumado, para ponerlo del otro lado, lo voy a restar.
Resuelvo;
Ahora, tengo un -9 multiplicándome la variable x, para poder deshacer esta multiplicación y dejar la variable sola, debo hacer la operación contraria; es decir, dividir por -9.
Resuelvo;
Y, si ya no se puede seguir, este sería mi resultado.
Para comprobar si es correcto, reemplazo en la ecuación original por el valor que ya he encontrado y las respuestas deben ser iguales.
