The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?
andriy [413]

Answer:

<h2>Yes, this is a right triangle.</h2>

Step-by-step explanation:

Hypotenuse always have the highest number than base and perpendicular.

Hypotenuse ( h ) = 15

Base ( b ) = 9

Perpendicular ( p ) = 12

Let's see whether the given triangle is a right triangle or not

Using Pythagoras theorem:

{h}^{2}  =  {p}^{2}  +  {b}^{2}

Plugging the values,

{15}^{2}  =  {12}^{2}  +  {9}^{2}

Evaluate the power

225  = 144 + 81

Calculate the sum

225 = 225

Hypotenuse is equal to the sum of perpendicular and base.

So , we can say that the given lengths of the triangle makes a right triangle.

Hope this helps..

Best regards!!

Write and solve the system of linear equations described by the application and then answer the question. One hundred sixty feet
Lena [83]

Answer:

80 ft x 40 ft

Step-by-step explanation:

Let 'L' be the length of the longer side and 'W' be the length of the shorter side (or the width).

The equations that compose the linear system are:

L+2W=160\\L=2W

Solving the system:

L+L=160\\L=80\\W=\frac{L}{2}\\W=40

The garden is a rectangle with dimensions 80 ft x 40 ft.

PLEASE HELP IM STRUGGLING!!!​
Mnenie [13.5K]

Answer:

  • 10. 0.99
  • 11. -60
  • 12. 5.5

Step-by-step explanation:

<u>Use the slope formula:</u>

  • m = (y2 - y1)/(x2 - x1)

10.

  • m = (6.24 - 3.27)/(5 - 2) = 2.97/3 = 0.99

11.

  • m = (240 - 360)/(3 - 1) = -120/2 = -60

12.

  • m = (8.84 - 6.09)/(7 - 2) = 2.75/5 = 5.5
