a triangle has side cequals6 and angles equals startfraction pi over 4 endfraction and equals startfraction pi over 3 endfractio
Diano4ka-milaya [45]

Answer:

a=\frac{12}{1+\sqrt{3}}

Step-by-step explanation:

c=6

Angle A= π/4

Angle B= π/3

Angle C = π - (π/4+π/3)= 5π/12

We want to determine side A.

Using Sine Rule

\frac{a}{Sin A}=\frac{c}{Sin C}

\frac{a}{Sin \frac{\pi}{4}}=\frac{6}{Sin \frac{5\pi}{12} }

a=\frac{6}{Sin \frac{5\pi}{12} } X Sin \frac{\pi}{4}

a=\frac{12}{1+\sqrt{3}}

a=4.39
