Mateo compró un artefacto gastando los 3/7 de su dinero, quedándole 360 soles, ¿Cuál era el dinero que tenía Mateo al inicio?
Debora [2.8K]

Answer:

840 soles

Step-by-step explanation:

Sea la cantidad de dinero que Mateo tenía al principio = x

Mateo compró un artefacto gastando 3/7 de su dinero, dejándole 360 ​​soles,

Por eso,

3/7 × x = 360 soles

3x / 7 = 360 soles

Multiplicar cruzada

3x = 7 × 360 soles

x = 7 × 360 soles / 3

x = 840 soles

Por tanto, el dinero que tenía Mateo al principio es de 840 soles

svetlana [45]

Answer:

cos 45 degree = A/H

cos 45 degree =  2 square root 2 / x

x = 2 square root 2 / cos 45 degree

x = 4

Sin 45 degree = O/H

Sin 45 degree = y/ 4

4 x Sin 45 degree = y

y = 2.83

or

we could use tan

tan 45 degree = O/A

tan 45 degree = y / 2 square root 2

2 square root 2 x tan 45 degree = y

y = 2.83

i hope this would elp a little bit.
