Answer: i dont really knw much bout this but i think its 22.71563

Explanation:

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

c = √b2 + a2 - 2ba·cos(C) = 22.71563

∠B = arccos(

c2 + a2 - b2

2ca

)

= 0.39114 rad = 22.411° = 22°24'39"

∠A = arccos(

c2 + b2 - a2

2cb

)

= 1.70325 rad = 97.589° = 97°35'21"

Area =

ab·sin(C)

2

= 112.5833

Perimeter p = a + b + c = 58.71563

Semiperimeter s =

a + b +c

2

= 29.35782

Height ha =

2×Area

a

= 8.66025

Height hb =

2×Area

b

= 22.51666

Height hc =

2×Area

c

= 9.91241

Median ma = √(a/2)2 + c2 - ac·cos(B) = 11.78983

Median mb = √(b/2)2 + a2 - ab·cos(C) = 23.89561

Median mc = √(c/2)2 + b2 - bc·cos(A) = 16.09348

Inradius r =

Area

s

= 3.83487

Circumradius R =

a

2sin(A)

= 13.11488
