Find the area

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary.

A = 50°, b = 30 ft, c = 14 ft


Correct result:

A =  160.87 ft2

Solution:

a2=b2+c2−2bccos⁡A a=302+142−2⋅30⋅14⋅cos⁡50∘=23.581 ft s=12(a+b+c)=33.7905 ft S=s(s−a)(s−b)(s−c)=160.87 ft2
