Determine whether the planes are parallel, perpendicular or neither. 2x â 4y + 3z = 5, x + 8y + 10z = 3
dexar [7]

The given two planes 2x + 4y + 3z = 5 and x + 8y + 10z = 3 are perpendicular to each other.

According to the given question.

We have two planes

2x - 4y + 3z = 5

and,

x + 8y + 10z = 3

Since, two planes are perpenicular if

a_{1} a_{2} + b_{1} b_{2} + c_{1} c_{2} = 0

Where a_{1}, b_{1} and c_{1} and a_{2}, b_{2} and c_{2} are the direction ratios of planes.

And the two planes are parallel to each other if

\frac{a_{1} }{a_{2} } =\frac{b_{1} }{b_{2} } = \frac{c_{1} }{c_{2} }

Here, the direction ratios of plane 2x + 4y + 3z = 5 are 2, -4, and 3  and the direction ratios of plane x + 8y + 10z = 3 are 1, 8, and 10

Now,

2(1) + (-4)(8) + 3(10)

= 2 - 32 + 30

= 0

Since, the sum of the product of the direction ratios of  the two palnes is 0. Therefore, the given two planes 2x + 4y + 3z = 5 and x + 8y + 10z = 3 are perpendicular to each other.

Help me this one out, pls?
Flura [38]

Answer:

∠ACD= 109°

Step-by-step explanation:

∠A=38

180- ∠A= ∠B+C

180-38= 2∠B( ∠B=∠C) ( angles opposite to equal sides are equal)

142=2∠B

∠B=71

∠ACD=∠A+∠B ( exterior angle property)

∠ACD= 38+ 71= 109°

Give two coterminal angles (one positive and one negative) and the reference angle -4 pi/5
kherson [118]

The coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.

<h3>What is coterminal angles?</h3>

Two different angles that have the identical starting and ending edges termed coterminal angles however, since one angle measured clockwise and the other determined counterclockwise, the angles' terminal sides have completed distinct entire rotations.

We have an angle:

-4π/5

To find the coterminal angle, add and subtract by 2π in the angle -4π/5

Coterminal angle:

= -4π/5 - 2π

= -14π/5

= -4π/5 + 2π

= 6π/5

Reference angle:

= π - 4π/5  (as the angle lies in the second quadrant)

= π/5

Thus, the coterminal angle for the -4π/5  are -14π/5 , 6π/5 and reference angle is π/5 respectively.
