(si no sabes no respondas por favor gracias)​

Answer 1

${a }^{2} = {8.5}^{2} + {9.8}^{2} - 2 \times 8.5 \times 9.8 \times \cos(52)$

a^2= 72.25+96.04-161.5cos(52)

A^2=72.25+96.04-127.26

A^2=41.03

A=6,41(apróx)

$\frac{8.5}{ \sin(b) } = \frac{6.41}{ \sin(52) }$

B= Arcsin[8.5sin(52)/6.41]

B=79,6°

C=180-52-79.6

C=48.4
