Answer:
A ≈ 31.7 cm²
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] × AC × BC × sinC
∠ C = 180° - 72° - 59° = 180° - 131° = 49° , then
A = [tex]\frac{1}{2}[/tex] × 7 × 12 × sin49°
= [tex]\frac{1}{2}[/tex] × 84 × sin49°
= 42 × sin49°
≈ 31.7 cm² ( to 1 dec. place )
