Answer:

11.48913

Step-by-step explanation:
A = V
B = X
C = D

Calculates b, ∠A, and ∠B based on given c, a, and ∠C.

∠A = arcsin $(\frac{a·sin(C)}{c})$ = 0.33984 rad = 19.471° = 19°28'16"

∠B = 180° - C - A = 1.23096 rad = 70.529° = 70°31'44"

b =  $\frac{c·sin(B)}{sin(C)}$ = 11.31371 = 8$\sqrt{2}$

Area = $\frac{ab·sin(C)}{2\\}$ = 22.62742

Perimeter p = a + b + c = 27.31371

Semiperimeter s = $\frac{a + b +c}{2}$ = 13.65685

Height ha = $\frac{2×Area}{a}$ = 11.31371

Height hb = $\frac{2×Area}{b}$ = 4

Height hc = $\frac{2×Area}{c}$= 3.77124

Median ma = $\sqrt{(a/2)2 + c2 - ac·cos(B)}$ = 11.48913

Median mb = $\sqrt{(b/2)2 + a2 - ab·cos(C)}$ = 6.9282

Median mc = $\sqrt{√(c/2)2 + b2 - bc·cos(A)}$ = 6

Inradius r = $\frac{Area}{s}$ = 1.65685

Circumradius R = $\frac{a}{2sin(A)}$ = 6
