solution

Area=absinx/2

=103x58×sin74.5°/2

=5974×sin74.5°/2

=5974×0.96/2

=5735.04/2

=2867.52

Acute Scalene Triangle

Side a = 103
Side b = 103.82695
Side c = 58
Angle ∠A = 72.932° = 72°55'54" = 1.2729 rad
Angle ∠B = 74.5° = 74°30'0" = 1.30027 rad
Angle ∠C = 32.568° = 32°34'6" = 0.56842 rad

Area = 2,878.36416
Perimeter p = 264.82695
Semiperimeter s = 132.41348
