Question

Please Help!!!!!!!!!!!

Answer 1

Answer:

C) $C=40$°, $a= 10.1$ , $c=6.72$

Step-by-step explanation:

$C= 180-105-35$

$C=40$°

Next using Sine rule,

$\frac{a}{sinA}=\frac{c}{sinC} =\frac{b}{sinB}$

where $A=105$°, $C=40$° , $B =35$° and $b = 6$.

$\frac{a}{sin105}=\frac{c}{sin40} =\frac{6}{sin35}$

Solve for a and c

$a= \frac{6}{sin35} (sin105)$

$a= 10.1$

$c = \frac{6}{sin35} (sin40)$

$c=6.72$
