Delicious77 [7]

The easiest way it to solve it.
${x}^{2} + 5x + 2 = 0$
You have
$\rho = 25 - 4 \times 1 \times 2 = 17$

8. Solve the following triangle for all missing sides and angles.

vova2212 [387]

Answer:

Parte1 :

∡B= 180 - (42 + 83)= 55°

Parte2 :

Using the law of sines : $\frac{sin 42}{a} = \frac{sin 55}{175}$ ⇔ $a = sin42 \frac{175}{sin 55}$ ⇔ a= 142.95

Parte3 :

Using the same law : $c = sin 83\frac{a}{sin 42}$ or $c= sin 83\frac{175}{sin 55}$ ⇔ c= 212.04
