Answer:
∠STR =
∠XYT
Step-by-step explanation:
The triangles are give congruent.△RST ≅ △TXY.
In congruent triangles corresponding angles are equal.The order of the letters in the congruent statement matters.
In the given statement the angles matching to ∠STR is ∠XYT.
Hence ,the equal angles in the congruent triangles are ∠STR = ∠XYT.

Explicação passo a passo:
Das opções fornecidas:
Todas as opções atendem à condição de uma matriz quadrada, pois todas têm o mesmo número de linhas e colunas (2 * 2)
Para ter uma matriz diagonal, todas as entradas fora da diagonal principal serão Zero.
Por outro lado, a matriz de identidade é um tipo especial de matriz quadrada com uma ao longo da diagonal principal.
Indo por essas condições apenas a matriz (b); atende às três condições.
Answer:
32 orders
Step-by-step explanation:
# of orders = 2^5=32 different orders
Answer:
(an -a1)/d +1 = n
Step-by-step explanation:
Undo what is done to n, in reverse order. When evaluating this expression, you ...
- subtract 1 from n
- multiply the difference by d
- add a1
When you undo these, you get ...
... an -a1 = d(n-1) . . . . . . subtract a1
... (an -a1)/d = n - 1 . . . . divide by d
... (an -a1)/d +1 = n . . . . add 1

<em>Comment on answer list</em>
Please note the use of parentheses in the answer here. These identify that the difference (an -a1) is what is divided by d. None of the offered answers has these parentheses, nor are they typeset in a way that would indicate the intent to divide (an -a1) by d. As given, none of the offered answers is correct.
