Determine the equation of the plane in the form

Bond [772]

A plane parallel to vectors <9, 6, 2> and <-8, -4, -5> is given by
$\left|\begin{array}{ccc}x&y&z\\9&6&2\\-8&-4&-5\end{array}\right| =0\\ (-30 + 8)x - (-45 + 16)y + (-36 + 48)z = 0\\-22x+29y+12z=0$

Since the plane passes through point (5, -5, 8), then
-22(5) + 29(-5) + 12(8) = -110 - 145 + 96 = -159

The required plane is -22x + 29y + 12z = -159
z = 11/6x - 29/12y - 53/4

Select all of the angles that are congruent to <5 plzzz helppp

kirill115 [55]

Answer:

Options A, D and F

Step-by-step explanation:

From the picture attached,

lines 'l' ad 'm' are the parallel lines and line 't' is a transversal intersecting each line at two different points.

From the angles formed at the points of intersection,

∠5 ≅ ∠8 [Vertical angles]

∠5 ≅ ∠4 [Alternate interior angles]

∠5 ≅ ∠1 [Corresponding angles]

Therefore, Options A, D and F will be the correct options.

Please help me! I got to get this done quickly! WILL GIVE BRAINLIEST

Answer:

x=29

Step-by-step explanation:

(x+3)+(x-1)+(x+1)=90

x+3+x-1+x+1=90

3x+3=90

3x=90-3

x=87/3

x=29

x+3=32

x+1=30

x-1=28

Checking

(x+3)+(x-1)+(x+1)=90

(29+3)+(29-1)+(29+1)=90

32+28+30=90

90=90
