Find the length of GV
levacccp [35]

Answer:

43.92

Step-by-step explanation:

First you need the measure of angle C

180 - 90 - 37 = 53 degrees

Then use the Law of Sines with the pair you know:

sin 90 / 55 = sin 53 / x

Solve the equation

x * sin 90 / 55 = sin 53

x * sin 90 = 55 * sin 53

x = 55 * sin 53/sin 90

x = 43.92

Dos amigos tienen lapices bordadores y tajadores en su cartuchera hay 8 borradores en total Mónica tiene el doble de lápices q F
aalyn [17]

Answer:

Mónica tiene 5 sacapuntas, 10 lápices y no borradores, mientras que Felipe tiene 5 lápices, 10 sacapuntas, 8 borradores

Step-by-step explanation:

El número total de borradores = 8

La cantidad de lápices que tiene Mónica = 2 × La cantidad de lápices que tiene Felipe

El número de sacapuntas que tiene Mónica = El número de lápices que tiene Felipe

El número de sacapuntas que tiene Felipe = 5 + El número de lápices que tiene

El número de suministros que tiene Monica = 18

El número de goma de borrar que tiene Monica = 0

Sea x el número de sacapuntas que tiene Monica, obtenemos;

El número de lápices que tiene Felipe = x

El número de sacapuntas que tiene Felipe = 5 + x

El número de lápices que tiene Monica = 2 · x

El número total de suministros que tiene Monica = x + 2 · x = 18

∴ x = 18/3 = 6

El número de sacapuntas que tiene Monica = 5

El número de lápices que tiene Monica = 2 · x = 2 × 5 = 10

El número de gomas de borrar que tiene Monica = 0

El número de lápices que tiene Felipe = x = 5

El número de sacapuntas que tiene Felipe = 5 + x = 5 + 5 = 10

El número de gomas de borrar que tiene Felipe = 8.
