Special Triangle: Solve for x and y.

Answer:

Step-by-step explanation:

Remark

First of all, all the units must be the same. Inches is probably the best unit to use.

Second the base line at the bottom must be completed. How long is it

Givens

Left side = 48 inches

Top = 3 yards

Right side = 5 feet.

Bottom = 1 yard + top

Bottom = 1 yard + 3 yards

Bottom = 4 yards

Perimeter = 144 + 60 + 108 + 48

Perimeter = 360 Inches.

Answer

Perimeter = 360 inches

Perimeter = 360 / 12 = 30 feet     There are 12 inches in a foot

Perimeter = 360 / 36 = 10 yards.  There are 36 inches in a yard

The question does not specify the units. Probably inches would work, but if a computer is marking your answer and you get it wrong, you are going to have to try the other two answers in turn.

Answer:

Step-by-step explanation:

                multiplying the first bracket with the second (step by step)

          = 1( 5z + 8z^2 - z^3) +2z ( 5z + 8^2 - z^3 )+3z^3 (5z + 8^2- z^3)

          = 5z + 8z^2 - z^3 + 10z^2 + 16z^3 - 2z^4 + 15z^4 + 24z^5 -3z^6

          =5z + 16z^2 + 15z^3 + 17z^4 + 24z^5 -3z^6

Check the picture below.

[tex]\cfrac{18}{18+x}~~ = ~~\cfrac{19.2}{38.4}\implies \cfrac{18}{18+x}~~ = ~~\cfrac{19.2}{2(19.2)}\implies \cfrac{18}{18+x}~~ = ~~\cfrac{1}{2} \\\\\\ 36=18+x\implies 18=x[/tex]

the sum of all the angles in a triangle is 180°

65°+20°+x = 180°

85°+x = 180°

x = 95°

The solution of the linear equation is x = 0.

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression.

Linear equations are the equations of degree 1.

The given linear equation is;

[tex]\rm 2(x-3)+ 9=3(x+ 1) +x[/tex]

The value of x is determined in the following steps given below.[tex]\rm 2(x-3)+9=3(x+1)+x\\\\2x-6+9=3x+3+x\\\\\ 2x+3=4x+3\\\\3-3=4x-2x\\\\0=2x\\\\x=0[/tex]

Hence, the solution of the linear equation is x = 0.

The mean if the scores was misread at 94 but it was 69 is 87.5

Mean is also known as average. It is mathematically represented as:

Mean  = Sum of data/Sample space

Given the following parameters

Mean = 88

Sample size = 50

Substitute

88 = Sum/50

Sum = 88(50)

Sum = 4400

If one of the scores was misread at 94 but it was 69, hence;

Sum + (94-69) = 4400
Sum + 25 = 4400
Sum = 4400 - 25
Sum = 4331
New mean = 4375/50
New mean = 87.5

Hence the mean if the scores was misread at 94 but it was 69 is 87.5

A parallelogram has an area of 37 square feet. If the height of the parallelogram is 4 feet, how many feet is the base?

The base of the given parallelogram is

Area of a parallelogram is defined as the product of its base and height respectively. Mathematically;

→ Area of parallelogram = base * height

By substituting the given values in the formula, we get the following results:

→ 37 = base * 4

→ base = 37/4

→ base = 9.25

Hence, the base of the given parallelogram is 9.25 feet.

Let's know something more about a parallelogram.

What is a parallelogram?

A parallelogram is a special type of quadrilateral whose opposite sides are parallel and hence its opposite angles are also parallel.

What is the formula of a parallelogram?

Let ‘B’ be the base and ‘H’ be the height of a parallelogram then its area is given by,

→ Area of parallelogram = B * H

What is unit of parallelogram?

The unit of a parallelogram is square units.

We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

The area of the composite figure is equal to the sum of area 1, area 2, and area 3

Area 1 - triangle

Area 2 - rectangle

Area 3  - semicircle

We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.

Step-by-step explanation:

As the points A, B, C and D lie on a circle, So, ABCD is a cyclic quadrilateral...

As, Sum of opp. ∠s in a cyclic quadrilateral = 180°

∴ ∠ADC + ∠ABC = 180°

=> ∠ADC + 100° = 180° => ∠ADC = 80°

Now,

Sum, of all angles in a traingle = 180°

In ΔACD, ∠CAD + ∠ADC + ∠ACD = 180°

=> ∠CAD + 80° + 40° = 180°

=> ∠CAD = 180° - 80° - 40° = 60°

As CT is tangent to the circle at the point C and CD is a chord of the circle, So

∠DCT = ∠CAD........(∠s in alternate segments are equal,,So ∠CAD = 60°)

=> ∠DCT = 60°

Answer:
