How does a airplane fly?

1 answer:

4 0

A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. ... The wings force the air downward and that pushes the plane upward.

Lines x and y are parallel and are cut by the transversal b. If the measure of angle 1 is 57°, what is the measure of angle 6? E

lana [24]

Answer:

$\angle6=123$

Step-by-step explanation:

Given

Lines x and y

Transversal b

$\angle 1 = 57$

Required

Find $\angle 6$

From the attachment, $\angle1$ and $\angle7$ are vertically opposite.

This means that

$\angle 1 =\angle 7 = 57$

Similarly

$\angle 7$ and $\angle 6$ are supplementary angles

So:

$\angle7 + \angle6=180$

Make $\angle6$ the subject

$\angle6=180-\angle7$

$\angle6=180-57$

$\angle6=123$

The relationship between $\angle1$ and $\angle6$ is that they are supplementary angles because:

$\angle6+ \angle1=180$

2. Peter, Jeff, and John, each perform subtraction incorrectly as follows:

grandymaker [24]

Answer:

peter: subtraction mistake at unit place . wrote 6 in place of 9

Jeff: subtraction mistake at tens place: wrote 4 while the correct digit is 3

peter: He has written 3 at unit place while correct digit is 2

John: he has carried 1 twice from 5 at hundred place and then subtracted 2 from it which gives value 1 at hundred place.

Step-by-step explanation:

we have to subtract 503 from 269

4 10 13

503

-269

____

234

Solution

since 3 is less than 9 , we take a carry from 0 but 0 cannot be carries so we take 1 carry from 5\

thus

5 becomes 4, 0 becomes 10,

now 10 can be give 1 carry to 3 at unit place, so 3 becomes 13

now 9 is subtracted from 13

13-4 = 9

this is the mistake of Peter

he has written 6 at unit place which should be

peter: subtraction mistake at unit place . wrote 6 in place of 9

____________________________________________________

since , 1 is carried from 10 at tens place, 9 is left at tens place

so we know subtract 6 from 9 at tens place

9-6 = 3

Here mistake is done by Jeff

Jeff: subtraction mistake at tens place: wrote 4 while the correct digit is 3

________________________________________________

at hundred place,

one is taken from 5 , hence 4 is left at hundred place

we have to subtract 2 from 4

4-2 = 2

hence,

Here, mistake done by both both Peter and jeff

peter: He has written 3 at unit place while correct digit is 2

John: he has carried 1 twice from 5 at hundred place and then subtracted 2 from it which gives value 1 at hundred place.
