Answer:

Step-by-step explanation:

Remember that the sum of any 2 sides of a triangle always must be greater than the length of the third side.

A. 9 + 5 = 14 so NO

B. 8 + 5 = 13 which is less than 14 so NO

C. 5 + 5 = 10 which is less than 14 so NO

D. 12 + 5 = 16 which is greater than 14.

12 + 5 > 14

14 + 12 > 5

5 + 14 > 12

It works for all 3. That means the answer is D.

A retangular athletic field is twice as long as it is wide. If the perimeter of the athletic field is 180 yards, what are its di

pishuonlain [190]

W= width
l= 2w= length

Perimeter of a Rectangle Formula
P= 2(l + w)
substitute 2w for l in equation

180= 2(2w + w)
multiply 2 by parentheses

180= 4w + 2w
combine like terms

180= 6w
divide both sides by 6

30 yards= w

LENGTH
2w= 2(30)= 60 yards

CHECK:
180= 30 + 60 + 30 + 60
180= 90 + 90
180= 180

ANSWER: the width is 30 yards and the length is 60 yards

Hope this helps! :)

Step-by-step explanation:

=>>. Hello mate. (◕ᴗ◕✿)

= Given :-

perimeter of traingle = 58 feet

 let the third side be. "X" feet

  longest side = (2x - 8) feet

 shorter side = (x + 2) feet

Perimeter of traingle = sum of all three sides

=> A/q. ,

( x ) + ( 2x - 8 ) + ( x + 2) = 58. ✓✓✓

 x + 2x - 8 + x + 2 = 58

=>. 4x - 6 = 58

=> 4x = 58 + 6

=> 4x = 64

=>. x = 64/4

 =|. x = 16 feet

length of third side = 16 feet

length of shorter side = 18 feet

length of longest side = 24 feet

 Hope it helps you.......

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Angles in a triangle add up to 180°

Since it's a right angled triangle one of it's angles is 90°

So for angle F we have

F + 25 + 90 = 180

F = 180 - 115

To find GH we use tan

tan 25 = FG / GH

FG = 7m

tan 25 = 7 / GH

GH = 7 / tan 25

To find FH we use sine

sin 25 = FG / FH

sin 25 = 7 / FH

FH = 7/sin 25

Hope this helps you

A packing company is doing an inventory of boxes. Their most popular box is display below: 2ft,(3x-5)ft,(2x-1)ft you can use the

Angelina_Jolie [31]

Answer:

The value of x = 3.

Length = 4 feet and Width = 5 feet

Step-by-step explanation:

Height of the box = 2 ft

Length of the box = (3x-5) ft

Width of the box = (2x-1) ft

Volume of the box = 40 cubic feet

Now, VOLUME OF CUBE = LENGTH x WIDTH x HEIGHT

$\implies 40 = 2 \times (3x-5) \times (2x-1)\\\implies 20 = 3x(2x-1)) -5 (2x-1) = 6x^2 - 3x -10x +5 = 6x^2 - 13x + 5\\\implies 6x^2 - 13x -15 = 0$

Now, solving for the value of x, we get:

$6x^2 -13 x - 15 = 6x^2 -18x + 5x - 15 = 0\\\implies6x(x-3) + 5(x-3) = 0\\\implies (x-3)(6x+5) = 0$

⇒ Either x-3 = 0, or ( 6x+5) = 0

⇒ Either x = 3, or x = -5/6

As x = SIDE OF A CUBE ,so it CANNOT be negative.

⇒x = 3

So, length = (3x-5) = 3(3) -5 = 9-5 = 4 units

Width = (2x-1) = 2(3) -1 = 5 units
