Using the formula A=1/2absinC, let's substitute a=6, b=12, and ∠C=48 degrees.
A=1/2 * 6 * 12 * sin(48 degrees)
Using a calculator, the sin(48 degrees) equals approximately 0.74314.
A=1/2 * 6 * 12 * 0.74314
A=3 * 12 * 0.74314
A=26.58714
Rounding to the nearest square yard, the area of △ABC is 27 square yards.
Use the formula
A=

absinC
to find the area of
△ABC
to the nearest square yard if
a=6 yards
,
b=12 yards
, and
∠C=48 degrees
.
