Answer:

let's consider the figure I edited and named angles as 1 2 and 3 respectively

so angle 1 = angle 2( vertically opposite)

therefore;

$14x - 77 = 9x - 27 \\ 14x - 9x = - 27 + 77 \\ 5x = 50 \\ x = 10(divide \: by \: 5)$

now

angle 2= 9(10)-27

=90-27

=63°

next is angle 3

i.e angle z

bye linear pair axiom

$z + 63 = 180 \\ z = 180 - 63 \\ z = 117$

<h2>answer is x=10° and z=117°</h2>

Given:

Given that the angles of the kite.

The opposite angles of the kite measures (3y + 14)° and (y + 50)°

We need to determine the value of y.

Value of y:

We know the property that the opposite angles are equal.

Thus, applying the property, we have;

$3y+14=y+50$

Subtracting both sides of the equation by y, we have;

$2y+14=50$

Subtracting both sides of the equation by 14, we get;

$2y=36$

Dividing both sides of the equation by 2, we get;

$y=18$

Thus, the value of y is 18.

How do you write 3.5 × 10^3 in standard form?

Nutka1998 [239]

Answer:

$3500$

Step-by-step explanation:

Given the following question:

$3.5\times10^3$

To convert a scientific notation into standard form we first need to keep in mind that the exponent in indeed a positive. Knowing this we know that the decimal point is going to move to the right.

Since the exponent is three, we know that the decimal point is going to move to the right THREE times.

$3.5\times10^3$
$3.5\times10^3=3.5.0.0.$
$3.5.0.0.=3500$
$=3500$

Your answer in standard form is "3500."

Hope this helps.
