Use slope formula: y2-y1/x2-x1

XZ: -5/9
YZ: 2/7
XY: -7/2

XYZ is a right triangle because two of these slopes have a product of -1.

(YZ and XY does). We are all busy these days.

P=2L+2W solve for L do the entire equation

VashaNatasha [74]

$HEY THEIR!!$

Taking commen 2 in RHS
p = 2 (L+W )

Divide by 2 on both sides.
p/2 = L+W

Subtract W on both sides.
p/2 - W = L

or L = p/2- W

Answer :-

9(3+√3) feet

Step by step explanation :-

A triangle is given to us. In which one angle is 30° and length of one side is 18ft ( hypontenuse) .So here we can use trignometric Ratios to find values of rest sides. Let's lable the figure as ∆ABC .

Now here the other angle will be = (90°-30°)=60° .

In ∆ABC ,

=> sin 30 ° = AB / AC

=> 1/2 = AB / 18ft

=> AB = 18ft/2

=> AB = 9ft .

Again In ∆ ABC ,

=> cos 30° = BC / AC

=> √3/2 = BC / 18ft

=> BC = 18 * √3/2 ft

=> BC = 9√3 ft .

Hence the perimeter will be equal to the sum of all sides = ( 18 + 9 + 9√3 ) ft = 27 + 9√3 ft = 9(3+√3) ft .

<h3>Hence the perimeter of the triangular pathway shown is 9 ( 3 + √3 ) ft .</h3>

What 3 write x3 x3x3x3x3 using exponents

Rainbow [258]

Not exactly sure wat u mean but if u are asking for 3x3x3x3x3 in exponents
it would be 3^5

On paper you wrtie 3 with a small 5 on the top right of the 3
the 5 means how many 3 u are multiplying
