The triangle that must appear to be obtuse mmust have one of its angle to be greater than 90 but less than 180 degrees:

Obtuse triangles are triangles that has one of theor angles to greater than 90 degrees.

Most obtuse triangles has two acute angles (angles less than 90 degrees) and a obtuse angle (angles between  90 and 180 degrees)

Hence the triangle that must appear to be obtuse mmust have one of its angle to be greater than 90 but less than 180 degrees:

Answer:

  A.  -3

Step-by-step explanation:

We recognize the given equation as being in point-slope form:

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

__

Comparing that to the given equation ...

  y -5 = -3(x -17)

we see that m = -3.

The slope of the line is -3.

Answer:

  (x, y) = (2 35/74, 2 25/74)

Step-by-step explanation:

The closest point on the line to the given point will be the point of intersection of the given line and a perpendicular through the given point.

__

A line perpendicular to ax+by+c=0 that goes through point (h, k) can be written as ...

  b(x-h) -a(y-k) = 0

For the given line and point, the perpendicular line will be ...

  7(x -2) +5(y -3) = 0

  7x +5y -29 = 0

Using the cross-multiplication method, we can find the solutions to the system of equations consisting of these two lines. It will be ...

  Δ = (-5)(5) -(7)(7) = -74

  Δx = (7)(-29) -(5)(-4) = -183

  Δy = (-4)(7) -(-29)(-5) = -173

  x = Δx/Δ = -183/-74 = 2 35/74 ≈ 2.4730

  y = Δy/Δ = -173/-74 = 2 25/74 ≈ 2.3378

Answer:

44.452

Step-by-step explanation:

Using the Pythagorean theorem you can use:

51^2 = 25^2 + w^2

2601 = 625 +w^2

w^2 = 1976

w = 44.452

Answer:

The width is 44.5in.

Step-by-step explanation:

25^2 + b^2 = 51^2

625 + b^2 =2601

b^2= 2601-625=1976

Square root it (1976)

Answer:

Step-by-step explanation:

3 ⅔

= 3 + 2/3

= 9/3 + 2/3    { LCM = 3 }

= ( 9 + 2 ) / 3

= 11/3

In the diagram,

Length ( l )= x m

Breadth ( b ) = 3 ⅔ m = 11/3 m

Given that area of the rectangle = 44 m²

Formula : -

Area of the rectangle = lb

lb = 44

x * 11/3 = 44

x = ( 44 * 3 ) / 11

x = 4 * 3

x = 12 m

Therefore,

the missing length = 12 m

Hey there!

3(x + 19) - 25/5

= 3(15 + 19) - 25/5

= 3(15) + 3(19) - 25/5

= 45 + 57 - 5

= 102 - 5

= 97

OR

3(x + 19) - 25/5

= 3(15 + 19) - 25/5
= 3(34) - 25/5

= 102 - 25/5

= 102 - 5

= 97

97 = 97 ☑️

Therefore, your answer is: 97

Answer:

Step-by-step explanation:

In the question we have given an expression that is 3 ( x + 19 ) - 25/5 and value of x is equal to 15 .

And we are asked to find the value expression when value of x is 15 .

Solution : -

[tex] \longmapsto \: 3( x+ 19) - \cancel{\frac{25}{5} }[/tex]

Step 1 : Substituting value of x in given expression and cancelling 25 by 5 :

[tex] \longmapsto \: 3(15 + 19) - 5[/tex]

Step 2 : Solving parenthesis by adding 15 and 19 :

[tex] \longmapsto \: 3(34) - 5[/tex]

Step 3 : By multiplying 3 with 34, we get :

[tex] \longmapsto \: 102 - 5[/tex]

Step 4 : Subtracting 5 from 102 :

102cm^2 - hope this helps

Step-by-step explanation:

find the area of the rectangle first in the middle

which equals 6 x 13 = 78cm^2

then find the traingles on the side

(6 x 4) / 2 = 12

there are 2 traingles so it would be 12 + 12 = 24

so all together the area would be 78 + 24 = 102cm ^2

New cost after Discount= $319.60

This is the list of choices that accompany that question:

A) The number is greater than 2. ---> FALSE BECAUSE IT INCLUDES GREATER THAN 10, AND 10 IS THE LAST NUMBER OF THE SET.

B) The number is not divisible by 5. ----> FALSE BECAUSE 10 IS DIVISIBLE BY 5.

C) The number is even or less than 12. ---> THIS CAN BE RIGHT BECAUSE 1) ALL THE NUMBERS SHOWN ARE EITHER EVEN OR LESS THAN 12 AND THE DEFINITION, AND 2) THE DEFINITION DOES NOT INCLUDE A NUMBER OUT OF THE NUMBERS SHOWN.

D) The number is neither prime nor composite. ---> FALSE BECAUSE ANY NUMBER IS EITHER PRIME OR COMPOSITE.

E) The square root of the number is less than 3. ---> FALSE BECAUSE THE SQUARE ROOT OF 10 IS GREATER THAN 2.
