Both base and height of the sail is 40 1/2 feet.
A sail is triangular in shape. Finding the area of a triangle is multiplying its base and height and dividing the product by 2.
A = 1/2 bh
Area = 40 1/2 or 40.50 sq. ft
Since base and height are equal.
40.50 x 2 = 81
bh = 81
bh = 81 ÷ 2
b = 40 1/2 ft
h = 40 1/2 ft
Answer:
b
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (3, 4 )
m =
= 
y =
x → b
1/4 • 2/2 = 2/8
2/8 + 5/8 = 7/8
Answer:
i believe its A.
Step-by-step explanation:
Because all youre doing is going down 4 units. make the 4 into a fraction , so 4/1. maing you equation -4 units down
