Answer:
The largest possible area of the deck is 87.11 m² with dimensions;
Width = 9.33 m
Breadth = 9.33 m
Step-by-step explanation:
The area of a given dimension increases as the dimension covers more equidistant dimension from the center, which gives the quadrilateral with largest dimension being that of a square
Given that the railings will be placed on three sides only and the third side will cornered or left open, such that the given length of railing can be shared into three rather than four to increase the area
The length of the given railing = 28 m
The sides of the formed square area by sharing the railing into three while the fourth side is left open are then equal to 28/3 each
The area of a square of side s = s²
The largest possible area of the deck = (28/3)² = 784/9 = 87.11 m² with dimensions;
Width = 28/3 m = 9.33 m
Breadth = 28/3 m = 9.33 m.
Answer:
P = 64 cm
Step-by-step explanation:
<C = 150° - 90° = 60°
AB = AC
∠B = ∠C = 60° } => ΔABC = EQUILATERAL TRIANGLE =>
=> BC = 10 cm
P = 10cm + 8cm + 6cm + 10cm + 6cm + 6cm + 8cm + 10cm
P = 3x10cm + 2x8cm + 3x6cm
P = 30cm + 16cm + 18cm
P = 64 cm
Answer:
37 degrees
Step-by-step explanation:
Tan x = 4.8/6.3
Tan x = 0.76
Tan^-1 (0.76) = 37 degrees
Answer:
No. The ladder is too steep.
Step-by-step explanation:
Length of ladder = 17 feet. This is the hypotenuse.
Side a of a right triangle = 16.6
To answer this, you need one of the trigonometric functions.
Opposite = 16.5
hypotenuse = 17
The function you need is the sine function.
Sin(theta) = opposite / hypotenuse
sin(theta) = 16.5 / 17
Sin(theta) = 0.97059
theta = sin-1(0.07059)
theta = 76.07
No the ladder is too steep.
