Answer 2

Answer

Right Scalene Triangle

Side a (X) = 14.91038 (To the nearest hundreth: 14.91)

Side b = 7

Side c = 13.16509

Angle ∠A = 90° = 1.5708 rad = π/2

Angle ∠B = 28° = 0.48869 rad

Angle ∠C = 62° = 1.0821 rad

Calculations:

alculated based on 2 given angles and 1 given side.

∠C = 180° - A - B = 1.0821 rad = 62°

a = b·sin(A)/sin(B) = 14.91038

c = b·sin(C)/sin(B) = 13.16509

Area =  

ab·sin(C)

 = 46.0778

Perimeter p = a + b + c = 35.07547

Semiperimeter s =  

a + b +c

c

 = 7

Median ma = √(a/2)2 + c2 - ac·cos(B) = 7.45519

Median mb = √(b/2)2 + a2 - ab·cos(C) = 13.62239

Median mc = √(c/2)2 + b2 - bc·cos(A) = 9.60884
