Question

resuelve los siguientes triangulos rectangulos​

Answer 1

Respuesta:

1.

$\alpha= 180-(90+65)= 25$

$Sin(65)= \frac{B}{15}$

$B= 15*Sin(65)$

$B= 13.59cm$

$Cos(65)= \frac{A}{15}$

$A= 15*Cos(65)$

$A= 6.33cm$

2.

$\beta= 180-(90+40)= 50$

$Tan(40)= \frac{12}{B}$

$B= \frac{12}{Tan(40)}$

$B= 14.30cm$

$Sin(40)= \frac{12}{C}$

$C= \frac{12}{Sin(40)}$

$C= 18.66cm$
