The value of x and y in the rhombus are 5 and 25 respectively.

The sum of angles of a rhombus is 360 degrees. The opposite angles of a rhombus is equal.

Therefore,

11x = 55

x = 55 / 11

x = 5

Therefore,

5y + 5y + 55 + 55 = 360

10y + 110 = 360

10y = 360 - 110

10y = 250

y = 250 / 10

y = 25

The distance can be expressed in equation d=5.3*[tex]10^{-4}m[/tex].

Given voltage of 96.6 V and electric field strength of 1.8 KV/cm.

We know that d=V/E

We have to find the distance in equation form.

We know that  electric field strength between the plates of a parallel plate capacitor is

E=V/d

Distance is the measurement between two sides or points.

where E=electric field strength

V=potential difference

d=distance between the plates

In equation form distance looks like:

d=V/E

from the question we are that V=96.6 V

E=1.8KV/cm.

Converting to V/m

E=180000V/m

d=96.6/180000

=0.00053

d=5.3*[tex]10^{-4}m[/tex].

Hence the distance can be expressed as d=[tex]5.3*10^{-4} m[/tex].

The two negative odd integers such that 5 times the first plus the square of the second equals -14 are: -3 and -1.

In a multiplication or division issue, an odd number of negatives will always result in a negative odd integer.

A negative odd integer carries a negative sign and is not exactly divisible by 2.

According to the question, an equation can be formed as follows:

[tex]5a+b^{2}=-14[/tex]

Here, a and b are the two negative odd integers.

Let a= -3 and b= -1,

[tex]5a+b^{2}=5(-3)+(-1)^{2}\\[/tex]

            = -15+1

Part 1

By the inscribed angle theorem, arc GFJ measures 55 degrees.

Part 2

By the inscribed angle theorem, arc FH measures 72 degrees.

Answer:

10.1%

Step-by-step explanation:

Interest = PRT/100

Interest = 77136.06 - 70060 = 7076.06

Interest = PRT/100

7076.06 = [(70060) × R × 1] / 100

7076.06 = 70060R/100

Cross multiply

(7076.06 × 100) = 70060R

707606 = 70060R

R = 707606/70060

R = 10.1%

Since the sum of both angles <ORQ and <SRQ is 180 degrees, hence the two angles that are supplementary are <ORQ and <SRQ

Supplementary angles are angles that sums up to 180 degrees..

Since the line SR bisects the line OQ, hence the angle <ORQ and <SRQ are equal and equal to 90 degrees each,

Answer:

x=70, y=40, z=70

Step-by-step explanation:

So whenever you have a straight line, the angle is going to be 180 degrees, and whenever you have multiple angles that make up one angle, the sum of the multiples angles is going to be the angle of the one angle.

So let's look at x. The 180 degree angle consists of 110 degrees and x, the sum of these two should add up to 180 degrees, you can set up an algebraic equation to solve for x, but you can also do some simple mental math to see that x=70, so that 110+70=180. You do the same thing for the other angles

For y, you simply need to know 140+y = 180 so y=40

For z there is two methods, you can use the fact that opposite angles are congruent, or you can use the fact that the sum of the interior angles of a triangle is 180 degrees. This means that x+y+z=180 and since we know that x=70 and y=40 then 70+40=z so 110+z=180 so z=70, which is also the same as the opposite angle, you could use either method although knowing that opposite angles are congruent is much more easier. It's called the vertical angles theorem.

The area of ​​the inner square to the area of ​​the outer square ratio is:  [tex]\frac{(a-b)^2+b^2}{a^2}[/tex]

Given a figure in which an inner square is inscribed inside the outer square.

The area of ​​a square is the product of the two sides of the square. Also known as side square.

Firstly, we will find the side of the inner square by finding the distance between the points (0,b) and (a-b,0)

S₁=√(a-b-0)²+(b-0)²

S₁=√(a-b)²+b²

Now, we will find the area of the inner square, we get

The area of the inner square=(side)²

A₁=(S₁)²

A₁=(√(a-b)²+b²)²

A₁=(a-b)²+b²square cm.

Further, we will find the side of the outer square by finding the distance between the points (0,0) and (a,0).

S₂=√(a-0)²+0²

S₂=√a²

S₂=a

Furthermore, we will find the area of the outer square, we get

The area of the outer square=(side)²

A₂=(S₂)²

A₂=a² square cm.

Hence, the area of the inner square to the area of the outer square ratio is [tex]\frac{(a-b)^2+b^2}{a^2}[/tex].
