Find all the missing elements:
pshichka [43]

Answer:

C = 21.78 and a= 8.88

Step-by-step explanation:

Here, sides b=7 and c=3

Also, Angle B=60

Angle B is between side c and a

It can be solve by cosine rule and sin rule

sin rule says,

\frac{a}{sinA}  = \frac{b}{sinB}  = \frac{c}{sinC} \\  \frac{a}{sinA}  = \frac{7}{sin60}  = \frac{3}{sinC}  \\ \frac{7}{sin60}  = \frac{3}{sinC}  \\ sinC = \frac{3}{7} \: sin60 = 0.3711537445 \\  \\ C =  21.78

cosine rule says,

{a}^{2}  =   {b}^{2}  +  {c}^{2}  + 2bc  \: cos(B) \\ {a}^{2}  =   {7}^{2}  +  {3}^{2}  + 2(7)(3)  \: cos(60) \\ {a}^{2}  =   49 +  9 + \:21 = 79 \\ a = 8.88
