Cuboid ABCDEFGH is shown

gtnhenbr [62]

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

$tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}$

$tan\angle ACF = \dfrac{FA}{AC}$

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

$\therefore tan\angle ACF = \dfrac{9.3}{8.63}$

$\therefore \angle ACF = arctan \left(\dfrac{9.3}{8.63} \right) \approx 47.14^{\circ}$

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

m_a_m_a [10]

Answer:

679959

Step-by-step explanation:

THE ANSWER IS 679959 BUT IF YOU ESTIMATE TO THE LAST DIGIT THE IT WOULD BE 700000 DUE TO 9 ROUNDING THE 7 TO A 8 AND THEN 8 EOUNDS THE 6 TO A 7 EVERYTHING ELSE BECOMES 0

Find the midpoint of AB A.(-2,-3) B.(16,4) C.(-2,-11) D.(4,-10)

zheka24 [161]

Answer:

(-2,-1)

Step-by-step explanation:

Using the graph find the coordinates for A and B.

A (-4,2) and B is (0,-4)

Midpoint formula is (x1 + x2)/2 , (y1+y2)/2

x value of the midpoint= (-4+0)/2 = -2

y value of the midpoint= (2 + -4)/2 = -2/2= -1

Midpoint is (-2, -1)
