Answer:
a) x = 10
Step-by-step explanation:
En este romboide, el angulo A es igual a el angulo C, y el angulo ABC es igual a el angulo CDA.
Entonces, el angulo C es 7x.
En un triangulo, los angulos se suman para ser 180 degrados. En el triangulo BCE, hay un angulo recto.
7x + 2x + 90 = 180
7x + 2x = 90
9x = 90
x = 10

Step-by-step explanation:
Answer:
27
Step-by-step explanation:
In this case we associate in total value from 225 to 100%, and they tell us that foreign currencies represent 88%, therefore, in quantity this would be:
225 * 88/100
198
The rest of the coins would then refer to the other coins I collect, which would be:
225 - 198 = 27
That is, 27 coins are the remaining coins.
Answer:
use the symmetric and transitive properties of congruence
Step-by-step explanation:
(1) ∠ABC ≅ ∠DEF and ∠GHI ≅ ∠DEF; given
(2) ∠DEF ≅ ∠GHI; symmetric property of congruence
(3) ∠ABC ≅ ∠GHI; transitive property of congruence (QED)
_____
<em>Additional comment</em>
The transitive property says if A≅B and B≅C, then A≅C. We used the symmetric property to swap sides of the congruence symbol with DEF and GHI to put the statement in the form to match the transitive property.
__
You will note we used the form ...
(statement number) statement; reason
with statement and reason separated by a semicolon.
