Answer:
319
Explanation:
\text{Area of a Triangle}\rightarrow \text{S.A.S.}
Area of a Triangle→S.A.S.
\text{Area}=\frac{1}{2}ab\sin C
Area=
2
1
absinC
From reference sheet.
\text{Area}=\frac{1}{2}(12)(55)\sin 75
Area=
2
1
(12)(55)sin75
Plug in values.
\text{Area}\approx318.756\approx 319
Area≈318.756≈31
