Find the area of the triangle given angle β=42∘, side a=7.2 ft, and side c=3.4 ft.

round the area to the nearest tenth and do not include units in your answer.

Area = 8.1902ft² (Rounded up to 4 decimal places)

Step-by-step explanation:

Let side a = 7.2ft, side b = 3.4ft and angle β = 42°

Area of the triangle will be given by:

1/2 × a × b × sinβ

Area = 1/2 × 7.2 × 3.4 × sin 42°

Area = 8.1902 ft² (Rounded up to 4 decimal places)

it's d
