Explain the following types of angles:
Acute angle
Right angle
Obtuse angle
Straight angle
Reflex angle
Complementary angles
Supplementary angles

Answer:

E. is 103 degree.

It's a vertical angle.

F. is 77 degree

the e and f makes a 180 degree. 180-103(aka e) = 77 degree

D. is 90 degree. it's perpendicular.

Answer:

Answer: w is 1.6 or. -5.6

Step-by-step explanation:

• I guess the question asks to find the value of w

[tex]{ \rm{3w + {w}^{2} + 1 = 10 - w }}[/tex]

• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0

[tex]{ \rm{ {w}^{2} + (3w + w) + 1 - 10 = 0 }} \\ \\ { \rm{ {w}^{2} + 4w - 9 = 0 }}[/tex]

• let's solve the equation using the quadratic formular

[tex] \hookrightarrow \: { \tt{w = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} }} \\ [/tex]

• Substitute following the mathematical operation rules:

[tex]{ \rm{w = \frac{ - 4 \pm \sqrt{ {4}^{2} - (4 \times 1 \times - 9) } }{(2 \times 1)} }} \\ \\ { \rm{w = \frac{ - 4 \pm \sqrt{52} }{2} }}[/tex]

• split the result:

[tex]{ \rm{either \: \{w = \frac{ - 4 + \sqrt{52} }{2} \} \: \: or \: \: \{w = \frac{ - 4 - \sqrt{52} }{2} \} }} \\ \\ { \rm{either \: \{w = 1.6 \} \: \: or \: \: \{w = - 5.6 \}}}[/tex]

Answer:

x=34º

Step-by-step explanation:

a line always = 180º

so y+81=180

y=99º

a triangle is also always 180º total

so x+y+47=180

x+99+47=180

x+47=81

x=34

Answer:

4x²+17x+2=52

Step-by-step explanation:

Step-by-step explanation: The given equation is 4x2 +17x+2. Here, lets substitute the value of x = 10. So, the equation simplifies to 4× (10)²+17(10)+2 , = (4 x 100) + 170 + 2 = 400 + 170 + 2 = 572 So, at x = 10, 4x²+17x+2=52

Step-by-step explanation:

Answer:

(2 , 3, 1)

Step-by-step explanation:

x + y + z = 6   ..(1)

3x - 2y + 2z = 2   ..(2)

-2x - y + 3z = -4  ..(3)

(1)*3-(2): 5y + z = 16  ..(4)

(1)*2+(3): y + 5z = 8  ..(5)

(4)*5-(5): 24y = 72         y = 3

(4): 5*3 + z = 16              z = 1

(1): x + y + z = x + 3 + 1 = 6        x = 2

The total cost of pizza and drinks, is an illustration of a linear function.

The model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]

The given parameters are:

[tex]\mathbf{Total =19}[/tex]

[tex]\mathbf{1\ pizza =10}[/tex]

[tex]\mathbf{1\ drink =d}[/tex]

The cost of 3 drinks will be 3d

The total cost would then be:

[tex]\mathbf{Total = 10 + 3d}[/tex]

Substitute 19 for Total

[tex]\mathbf{10 + 3d = 19}[/tex]

Rewrite the above equation as:

[tex]\mathbf{3d + 10 = 19}[/tex]

Hence, the model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]

Given : The length of a rectangle is 5cm more then the width. The perimeter of the rectangle is 38cm. Find the length and width of the rectangle?

Solution : According to the question, here we are given that the length if the rectangle is 5m more than its breadth and so the perimeter of the rectangle is 38cm. So, for this let's check the steps below

Let's assume the breadth be B

So, as we got that length is 5cm more than Breadth which is B + 5cm

Perimeter is 38cm

★ Perimeter = 2(Length + Breadth) ★

Finding Length

Length = B + 5cm = 7cm + 5cm = 12cm

Finding Breadth

Breadth(Width) = B = 7cm

Therefore, Width is 7cm whereas Length is 12cm

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x-60

 ———— • 5 = 0 • 5

  5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x-60  = 0

Solving a Single Variable Equation:

4.2      Solve  :    x-60 = 0

Add  60  to both sides of the equation :

                     x = 60
