En el triángulo rectángulo ABC, recto en “B”, SI Tg C = 3/5, hallar el valor “cosec A”

Cosec(A) = 3.64

Step-by-step explanation:

Ok, tenemos un triangulo rectángulo.

Sabemos que B = 90° y que  

tg(C) = 3.5

entonces:

Atg(Tg(C)) = C = Atg(3.5) = 74.05°.

Nosotros también sabemos que la suma de todos los ángulos interiores de un triangulo es igual que 180°

entonces:

A + B + C = 180°

A + 90° + 74.05° = 180°

A = 180° - 90° - 74.05° = 15.95°

Entonces Cosec(A) = Cosec(15.95°) = 1/sin(15.95°) = 3.64

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
