Answer

132 degrees

Step-by-step explanation:

Strategy: Find angle DEB and using that fact that DEB + DEF is 180 degrees to find angle DEF

The sum of the four angles of any quadrilateral is 360 degrees.

Since three angles are given, we can use that to find the fourth.

360-(147+93+72)=size of angle DEB. Solving, you get angle DEB is 48.

Also, knowing that segment BF is a straight line, it means that angle DEB + angle DEF is equal to a straight angle (180 degrees).

DEB+DEF=180

48+DEF=180

DEF=180-48=132 degrees.

Thus, angle DEF is equal to 132 degrees.

Answer:

y + 16 = -1(x + 3)²

Step-by-step explanation:

Looking at the graph, parabola vertex opens upwards with x intercepts as -5 and -1.

Thus, the line of symmetry will be;

x = (-5 + (-1))/2 = -3

Looking at the graph we can see that the vertex when traced to the x - coordinate will be 3 which is same with what we got.

Now, the general form of the equation will be;

y - h = a(x - k)²

where (k,h) is the vertex coordinate

Thus, k = -3

So;

y - h = a(x - (-3))²

>> y - h = a(x² + 6x + 9) =

>> y = ax² + 6ax + 9a + h

When, x = 0

y = 9a + h

From the graph, we can see that the y-intercept is y = -25

Thus;

9a + h = -25

From the graph, h which is the y-coordinate of the vertex = -16

Thus;

9a - 16 = - 25

9a = -25 + 16

9a = -9

a = -9/9

a = -1

Thus, the equation is;

y - (-16) = -1(x - (-3))²

>> y + 16 = -1(x + 3)²

Answer:

$34.56

Step-by-step explanation:

First, find the discount price.

20% of 40

20/100 x 40= $8

Deduct the discount from the original price.

40 - 8 = $32

This is the discount price.

Now, find 8% (tax) of the price.

8/100 x 32 = $2.56

Add it to the price.

32 + 2.56 = $34.56

Hope this helps!

Option 'D' is the correct option.

The correct diagram for Beyunka creating is given in option D.

What is Right triangle?

When an angle of a triangle is measure 90 degree then the triangle is called a right triangle.

Given that;

Beyunka is creating a diagram to prove that certain triangle is a right triangle.

Since, The right triangle is satisfy the Pythagoras theorem.

Now, By option D;

Let sides of a triangle are,

Hypotenuse (H) = c

Perpendicular side (P) = a

Then, The base of the right triangle = √H² - P² = √c² - a²

And, All other diagrams are not satisfy the Pythagoras theorem.

=============================================

Explanation:

For now, ignore the smaller rectangle and its dimensions. The larger rectangle has sides 3x and x+5, which I'll call the length and width.

L = 3x

W = x+5

The perimeter of any rectangle is P = 2(L+W). Plug in those values of L and W, and also the given perimeter P = 66. Isolate x.

P = 2(L+W)

2(L+W) = P

2(3x+x+5) = 66

2(4x+5) = 66

8x+10 = 66

8x = 66-10

8x = 56

x = 56/8

x = 7

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

Now that we know x, we can find the area of the rectangles.

As you probably can guess, the shaded region is the difference of the two areas.

A = area of larger rectangle

A = (length)*(width)

A = (3x)*(x+5)

A = (3*7)*(7+5)

A = 252

B = area of smaller rectangle

B = (x+3)*(x+2)

B = (7+3)*(7+2)

B = 90

C = area of shaded region

C = A - B

C = 252 - 90

C = 162 square units is the area of the shaded region.

Answer:

Option "D" is the correct answer to the following question.

Step-by-step explanation:

Given:

Length of painting = 25 inch

Height of painting = 16 inch

Width of frame = w inch

Find:

Area of Picture with frame

Computation:

New length of painting = 25 + w + w

New length of painting = 25 + 2w inch

New height of painting = 16 + w + w

New height of painting = 16 + 2w

Area = l x b

So,

Area of Picture with frame = [25 + 2w][16 + 2w]

Area of Picture with frame = 400 + 50w + 32w + 4w²

Area of Picture with frame = 4w² + 82w + 400
