Answer:
El reloj está marcando:
las 4:00 horas
Step-by-step explanation:
El reloj avanzó a su mismo ritmo pero en sentido contrario a partir de las 6:45
si ahora son las 9:30 el reloj marca:
9:30 = 9horas 30minutos = 9h 30'
6:45 = 6horas 45minutos = 6h 45´
1 hora = 60'
9h 30' = 8h + 60' + 30' = 8h + 90' = 8h 90'
entonces:
8h 90'
- 6h 45'
= 2h 45
entonces el reloj está marcando 2h 45' menos que la hora en que se dañó.
por tanto:
6h 45'
- 2h 45'
= 4h 00'
El reloj ahora está marcando las
4 horas en punto.
Add 9 to both sides
So
33=2x
Divide both sides by 2
So
X=16.5
It's 3.74 rounded up to 4 the reason why it is that answer is because the formula to a triangle's Hypotenuse is A squared + B squared = C squared
