Measurements of a triangle

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 answer:

S =  160.87 ft2

Step-by-step explanation:

A=50  b=30 ft c=14 ft   a2 = b2+c2  2bc cos A a=b2+c22 b c cosA=b2+c22 b c cos50° =302+1422 30 14 cos50° =302+1422 30 14 0.642788=23.58089 ft  s=2a+b+c=223.5809+30+1433.7904 ft  S=s (sa) (sb) (sc)=33.7904 (33.790423.5809) (33.790430) (33.790414)=160.87 ft2
