Answer:
-2.7
Step-by-step explanation:
The order would be
-3.3, -2.7, -2, -1.1, -1, 0
You can count it by remembering when the number that is the biggest but HAS a negative sign would be at the left and the number that is the biggest with NO negative sign would be at the right
Answer:
Step-by-step explanation:
either do 23 x23
or
23 x 16 ( do this first )

Answer:
The angle formed between CF and the plane ABCD is approximately 47.14°
Step-by-step explanation:
The given parameters are;
BC = 6.8
DE = 9.3
∠BAC = 52°
We note that the angles formed by the vertex of a cuboid are right triangles, therefore, by trigonometric ratios, we get;
sin∠BAC = BC/(The length of a line drawn from A to C)
∴ The length of the line drawn from A to C = BC/sin∠BAC
The length of the line drawn from A to C = 6.8/sin(52°) ≈ 8.63
∴ AC = 8.63
By trigonometry, we have;
The angle formed between CF and the plane ABCD = Angle ∠ACF


In a cuboid, FA = BG = CH = DE = 9.3


The angle formed between CF and the plane ABCD = Angle ∠ACF ≈ 47.14°
