What is the area of the triangle below?
14
23.6
***
12

Answer:

3

Step-by-step explanation:

Evaluate F(x) = –x^2 – 4x by substituting -1 for x:

              F(-1) = –(-1)^2 – 4(-1)

This becomes:

               F(x) = –1 + 4  =  3

Answer:

Hey mate.....

Step-by-step explanation:

This is ur answer.....

M.A 1 = 180 - 125 ( Supplementary angle)

M.A 1 = 55

M.A 3 = 125 (Vertically Opposite Angles)

M.A 4 = 55 (Vertically Opposite Angles)

M.A 5 = 55 ( Corresponding Angle)

M.A 6 = 125 ( Corresponding Angle)

M.A 7 = 125 ( Vertically Opposite Angle)

M.A 8 = 55 ( Vertically Opposite Angle)

Answer:

∠1 = 55°

∠3 = 125°

∠4 = 55°

∠5 = 55°

∠6 = 125°

∠7 = 125°

∠8 = 55°

Step-by-step explanation:

This is the detective case for vertical angles!!(dun-dun-dun!!!!)

Ok the info we have is that Angle 2 is 125°

Ok, quick,  take ten seconds, the other group might take the victory coin. What is the vertical angle for angle 2?

-----

3! Correct

3 is the vertical angle because it is one part of the pair of opposite angles made by two intersecting lines.

3 is now 125°

The sum of all angles 1,2,3,4 is 360°

360° - 125° - 125° = 110°

110° / 2 (because 1 and 4 are vertical, they are equal) = 55°

1 = 55° and 4 = 55°

Lets do this for 5,6,7, and 8

Angle 1 = angle 5 because it is the law of same side interior(corresponding) angles, or they are the same because the lines are parallel to each other.

So angle 5= 55°

then angle 8 = 55°

6 = 125° and 7 = 125°

Yay you beat the other team. Great job you win a victory coin(which basically is something that is absolutely nothing)

Answer:

61°

Step-by-step explanation:

In order for triangle LMN and PQR to be congruent, angle M and angle Q must equal. thus, we can set 2x-26=x+16

with basic algebraic manipulation, x=42. we then plug it back into the angle M or Q, getting angle M/Q= 58°

since this is a isoceles, the 2 base angle are identical, so 180= 58+2(angle P)

thus, angle P= 61

The minimum amount of fabric needed for a sandbox is,

⇒ 72 feet²

We have to given that;

A sandbox in the shape of a trapezoid is show below.

And, a cover is to be made for the sandbox.

Hence,

The minimum amount of fabric needed for a sandbox is,

⇒ Area of fabric = 9 × 7 + (1/2 × 9 × 2)

                         = 63 + 9

                         = 72 feet²

Thus, The minimum amount of fabric needed for a sandbox is,

⇒ 72 feet²

Answer:

B) 50

Step-by-step explanation:

<A = x + 53

x + 53 + x + 83 + 50 = 180

2x + 186 = 180

2x = -6

x = -3

<A = x + 53

Answer:

1.) 138

2.) 55

Step-by-step explanation:

1.) 8 x 6 = 48 x 2 = 96

   (middle) 8 x 3 = 24

   (triangles) 6 x 3 = 18 divided by 2 = 9 x 2 = 18

96 + 24 + 18 = 138

2.) (middle) 5 x 5 = 25

    (triangles) 5 x 3 = 15 divided by 2 = 7.5 x 4 = 30

     30 + 25 = 55

Answer:

A. Length

Step-by-step explanation:

Betty wants to put new cabinets in her kitchen. She measures one side of her kitchen and finds it measures 18 meters.

Which measurement did Betty find?

A. Length

B. Perimeter

C. Area

The measurements Betty found is the length of the cabinet

A side of the cabinet is equivalent to the length of such cabinet

To find the perimeter of the cabinet, it requires the addition of all the sides of the cabinet.

To find the area of the cabinet, it requires the multiplication of two different sides of the cabinet.

Therefore, Betty has only measured the length of the cabinet
