WHAT IS THE AREA OF THE TRIANGLE???

Answer:

Step-by-step explanation:

Answer:

4 and 7

Step-by-step explanation:

let's call the first number 'x' and the second number 'y'

so from the question we obtain two equations:

2x+y=15 ..... equation 1 and

x+y=11 .........equation 2

rearranging equation 2

y=11-x

now let's substitute it to equation 1

2x+11-x=15

x=15-11

x=4

now solving for y(let's take equation 2)

4+y=11

y=11-4

y=7

Answer:110

Step-by-step explanation:

ANSWER:

x = -3

Step-by-step explanation:

55+54+x+74=180

109+x+74=180

183 + x = 180

x = -3

Answer:

Step-by-step explanation:

All triangles have 180 as the sum of the 3 interior angles.

x + 74 + 55 + 54 = 180            Combine

x + 183 = 180                           Subtract 183 from both sides.

x = 180 - 183                            Combine

x = - 3

You probably have been told that there is no such thing as a minus angle, and that's true. The angle isn't minus. Just x is. The size of the angle is

Angle size = 74 - 3 = 71

Now try adding them together

55 + 54 + 71 = 180 which is what it should come to  

Answer:

1. 130°

2. 65°

3. 158°

4. 135°

5. 135°

Step-by-step explanation:

Let x be the unknown angle

1. Congruent angles are marked with a dash

Sum of interior angles of a 5-sided polygon is 540°

⇒ x + 90 + 110 + 100 + 110 = 540

⇒ x = 130°

2. Congruent angles are marked with a dash

Sum of interior angles of a triangle is 180°

⇒ 2x + 50 = 180

⇒ x = 65°

3. Sum of interior angles of a 5-sided polygon is 540°

⇒ x + 76 + 90 + 90 + 126 = 540

⇒ x = 158°

4. Congruent angles are marked with a dash

Sum of interior angles of a 6-sided polygon is 720°

⇒ 4x + 90 + 90 = 720

⇒ x = 135°

5. Congruent angles are marked with a dash

Sum of interior angles of a 8-sided polygon is 1080°

⇒ 8x = 1080

⇒ x = 135°

Answer:

9.4

Step-by-step explanation:

You can figure out the Hypotenuse length with only 1 angle and side length using the following formula:

Adjacent/cos(theta)

Which gives 9.433, which equals the hypotenuse.

Rounded up gives 9.4

The line which is the best model for the data in a scatter plot is: D. A scatterplot with an x axis labeled, variable A from twenty to sixty in increments of ten and the y axis labeled, variable B from twenty to forty in increments of five with a negative trend line through the middle of eight points.

A scatter plot can be defined as a graph which uses Cartesian coordinates (x-axis and y-axis) to display the values of two (2) variables, with the resulting points revealing any correlation between the data.

A trend line refers to an statistical (analytical) tool that is used in conjunction with a scatter plot, so as to determine whether or not there's any correlation between a data.

For example, a scatterplot with an x-axis with its points ranging from twenty (20) to sixty (60) in increments of ten (10) while the y-axis has  its points ranging from twenty (20) to forty (40) in increments of five (5) with a negative trend line through the middle of eight (8) points i.e above and below the trend line.

Answer:

D is your correct answer

Step-by-step explanation:

This is a quadratic equation which means that it has two roots which is your X-Intercepts. As seen on the graph, your X-intercepts are 3 and 5 which are your roots. Simple bring them over to the other side so you have (X-3) and (X-5)

You now multiply them into each other:

(X-5)×(X-3)=0

: X^2-8x+15

Answer:

D)  y = x² - 8x + 15

Step-by-step explanation:

x-intercepts are at x = 3 and x = 5

⇒ y = (x - 3)(x - 5)

⇒ y = x² - 8x + 15

We have,

We know that,

Area of semicircle

[tex]\bold{\pink{ = }}{\bold{\pink{\dfrac{1}{2}}}}{\bold{\pink{\pi{r^{2}}}}}[/tex]

Subsitute the required values,

[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{\dfrac{4^{2}}{2}}}}[/tex]

[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{\dfrac{16}{2}}}}[/tex]

[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{8}}}[/tex]

[tex]\sf{ = }{\sf{\dfrac{176}{7}}}[/tex]

Area of parallelogram

[tex]\bold{\red{ = Base }}{\bold{\red{\times{ Height }}}}[/tex]

Subsitute the required values,

[tex]\sf{ = 10 }{\sf{\times{ 6 }}}[/tex]

[tex]\bold{ = 60 \:in.^{2}}[/tex]

Thus, The area of parallelogram is 60 in.

Area of the given figure

= Area of semicircle + Area of parallelogram

Subsitute the required values,

[tex]\sf{ = 25.142 + 60 }[/tex]

[tex]\sf{ = 85.142\: in^{2}. }[/tex]

When round off to nearest Hundred

[tex]\bold{ = 85.1 in.^{2}}[/tex]

Hence, The area of the given figure is 85.1 inches² .

The area of the composite figure to the nearest hundredth is 85.12 inches squared.

The area can be defined as the space occupied by a flat shape or the surface of an object.

Therefore, the figure is a composite figure, it has a parallelogram and a semi circle.

area of the figure = area of parallelogram + area of semi circle

area of parallelogram = bh

where

b = 10 inches

h = 6 inches

area of parallelogram = 10 × 6 = 60 inches²

area of semi circle = πr²  / 2

where

Therefore,

r = 8 / 2 = 4 inches

area of semi circle = 3.14 × 4² / 2

area of semi circle = 3.14 × 16 / 2

area of semi circle = 50.24 / 2

area of semi circle = 25.12 inches²

area of the figure = 60 + 25.12 = 85.12 inches²
