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)

idk im srry

step-by-step explanation:

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
