13260 square inches
Step-by-step explanation:
In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch
The formula to solve the above question is
1/2absinθ
a = 100 inches
b = 740 inches
θ = 159°
The area of the triangle =
1/2 × 100 × 740 × sin 159°
= 13259.61 square inches
Approximately = 13260 square inches
Therefore, the area of DEF = 13260 square inches
