Answer:

2nd option

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

121.8° is an exterior angle of the lower triangle , then

∠ 2 + 17.3° = 121.8° ( subtract 17.3° from both sides )

∠ 2 = 104.5°

------------------------------------

∠ 2 is an exterior angle of the upper triangle , then

∠ 1 + 37.1° = 104.5° ( subtract 37.1° from both sides )

∠ 1 = 67.4°

Answer:

[tex]y=\dfrac{2xz}{(z-x)}[/tex]

Step-by-step explanation:

Given:

[tex]\dfrac{1}{x}=\dfrac{2}{y}+\dfrac{1}{z}[/tex]

[tex]\implies \dfrac{2}{y}=\dfrac{1}{x}-\dfrac{1}{z}[/tex]

[tex]\implies \dfrac{2}{y}=\dfrac{z-x}{xz}[/tex]

[tex]\implies 2xz=y(z-x)[/tex]

[tex]\implies y=\dfrac{2xz}{(z-x)}[/tex]

When x = 5 and z = 10:

[tex]\implies y=\dfrac{2(5)(10)}{(10-5)}[/tex]

[tex]\implies y=\dfrac{100}{5}[/tex]

[tex]\implies y=20[/tex]

The length of the flag measure in meters is,

⇒ 1.52 meters

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

We have to given that;

A flag is 152 centimeters long.

Now,

We know that;

1 centimeters = 1/100 meters

Hence, We get;

The length of the flag measure in meters is,

⇒ 152 centimeters

⇒ 152/100 meters

⇒ 1.52 meters

Thus, The length of the flag measure in meters is,

⇒ 1.52 meters

Answer:

Step-by-step explanation:

Area of figure = area of trapezoid + area of rectangle

A(rectangle) = 18 x 5 = 90 cm2
A(trapezoid) = (10+18) x (13-5) : 2 = 112 cm2

A(figure) = 112 + 90 = 202 cm2

The total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.  

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

She keeps some in a display case and the rest on the wall. 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

Let x be the total number of toy cars in Enola's collection:

69% of x = x - 155

0.69x = x - 155

0.31x = 155

x = 500

Thus, the total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

9c^2 - 30cd + 25d^2

Step-by-step explanation:

(3c - 5d)^2

= (3c - 5d) (3c - 5d)

= [3c * 3c] + [3c * -5d] + [-5d * 3c] + [-5d * -5d]

= 9c^2 - 30cd + 25d^2

Hello!

75,000 - 10% of 75,000

= 75,000 -(10*75,000)/100

=  75,000 -7,5 => 67,500

67,500 - 10% of 67,500

= 67,500- ( 10*67,500)/100

=67,500 - 6,75 = 60,750

60,750 -10%  of 60,750

= 60,750-( 10*60,750)/100

= 60,750 - 6,075 => 54,675

Solution:

Let's take the greatest two-digit number as an example.

Proving...

Since the difference between the greatest two-digit number and the product of its digits is a two-digit number, the difference between the other two-digit numbers '10, 11, 12.... 97, 98' and the product of its digits will always be a two-digit number, as the product of its digit is less than the two-digit number.

Hence proved. ✔✔

Step-by-step explanation:

Let the two-digit number is [tex]xy[/tex]

This can be written as:

The difference between the number and product of its digits is:

Rewrite this as below:

d = 10x - xy + y - 10 + 10 =

     x(10 - y) - (10 - y) + 10 =

     (x - 1)(10 - y) + 10

We see that:

The value of d is then:

Answer:

Rachel will need 49 meters of fencing.

Step-by-step explanation:

From Geometry we know that area of the square ([tex]A[/tex]), measured in square meters, is represented by the following formula:

[tex]A = l^{2}[/tex] (Eq. 1)

Where [tex]l[/tex] is the side length of the square, measured in meters.

The length of the square is now cleared:

[tex]l = \sqrt{A}[/tex]

If we know that [tex]A = 150\,m^{2}[/tex], then the side length is:

[tex]l =\sqrt{150\,m^{2}}[/tex]

[tex]l \approx 12.247\,m[/tex]

The total amount of fencing is equal to the perimeter of the square ([tex]p[/tex]), measured in meters, that is:

[tex]p = 4\cdot l[/tex] (Eq. 2)

If we know that [tex]l = 12.247\,m[/tex], then the perimeter of the square is:

[tex]p = 4\cdot (12.247\,m)[/tex]

[tex]p = 48.988\,m[/tex]

As fencing is cut into 1-m lengths, we need to round this number up to the nearest integer. That is:

[tex]p = 49\,m[/tex]

Rachel will need 49 meters of fencing.
