Given: In ΔDEF and ΔDGF, Side DF is common.
To prove congruent of the triangle, we must require the minimum three conditions; like two sides and one angle of one triangle should be equal to the other triangle. OR Three sides of one triangle should be equal to the other triangle. OR Two angles and one side of one triangle should be equal to the other triangle. etc.
As per given question, to prove congruent of given triangles by SAS property then we should have given two sides and one angle of one triangle should be equal to the other triangle as additional information.
Since, In ΔDEF and ΔDGF, Side DF is common. So, we should require only one side and one angle that should be equal to another triangle.
Answer:
The median grade would be 89
Step-by-step explanation:
To find the median, first put the numbers all in ascending order.
79, 80, 86, 92, 95, 96
Now isolate the middle term or terms. Since there is an even amount of numbers, we pick the two in the middle. To find the median, we take an average of those terms.
(86 + 92)/2 = 89
El area total de los 4 cuadrados es 71.86 centimetros cuadrados.

¿Cual es el area total de los 4 cuadrados?</h3>
Recordar que para un cuadrado de lado L, el area es:
A = L^2
Sabemos que el radio del circulo es R = 10.6cm, entonces para los dos cuadrados grandes tenemos:
L = 10.6cm/2 = 5.3cm
Es decir, cada uno de esos cuadrados tiene un area de:
A = (5.3cm)^2 = 28.09 cm^2
Notar que para los cuadrados pequeños, el lado es mayor que la mitad del cuadrado grande, midiendo el lado y comparandolo, veremos que para estos dos cuadrados:
L = 2.8cm
Entonces el area de cada uno de estos sera:
A = (2.8cm)^2 = 7.84cm^2
El area total es:
area = 2*(28.09 cm^2 + 7.84cm^2) = 71.86cm^2

Answer:
scale factor: 1.16
perimeters: 21.84 ft and 25.36 ft
Step-by-step explanation:
The area for an octagon is as follows:
solved for "l":
now we calculate the value of each side:
l1 = 2.73
l2 = 3.17
The scale would be:
3.17 / 2.73 = 1.16
And the value of the perimeter of the first would be:
2.73 * 8 = 21.84
and the second:
3.17 * 8 = 25.36
