First you must know that the sum of the interior angles of a triangle are 180. Once you know that, you just simply add 98+x=180 (you can use an variable as you see fit, doesn't need to be x). And then you simply solve for x by dividing 98 on both sides leaving you with 82.
Answer: A line with a slope of 2
Step-by-step explanation: the slope of the line is -1/2 so the negative reciprcal of the slope is 2 (It would be perpendicular to it)
i used m=y2-y2/x2-x1 to figure ou the slope and -(x/y) as the negative reciprcal for the perpendicular line.
The dimension of the length and width of the rectangle with the given perimeter are 33ft and 16.5ft respectively.
<h3>What are the dimensions of the rectangle?</h3>
Perimeter of rectangle is expressed as;
P = 2( l + w )
Given that;
- Perimeter P = 99ft
- Let width w = x
- Length l = 2x
We substitute into the formular above.
P = 2( l + w )
99ft = 2( x + 2x )
99ft = 2x + 4x
99ft = 6x
x = 99ft/6
x = 16.5ft
Width = x = 16.5ft
Length = 2x = 2( 16.5ft ) = 33ft
Therefore, the dimension of the length and width of the rectangle with the given perimeter are 33ft and 16.5ft respectively.
