Answer:
4x - 16
Step-by-step explanation:
A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
the perimeter of a triangle = sum of the side lengths
let the unknown length be represented with y
13x - 21 = 4x + 3 + 5x - 8 + y
13x- 21 = 9x - 5 + y
Make y the subject of the formula
13x - 21 - 9x + 5 = y
4x - 16 = y
the side length = 4x - 16
Answer: u just need to do 335.0/0.67
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Adding positively to an x moves it right, and negative moves left. Adding to a y moves it up, and subtracting moves it down.


7) You have the opposite. You need the adjacent.



x = 7.79289... =
<h2>7.8</h2><h2 />
8) You have the hypotenuse. You need the Opposite.


x = sin37 × 13
x = 7.8235... =
<h2>7.8</h2><h2 />
9) You have the hypotenuse. You need the opposite.


x = sin59 × 11
x = 9.4288.... =
<h2>9.4</h2><h2 />
10) You have the hypotenuse. You need the opposite.


x = sin53 × 11
x = 8.7459.... =
<h2>8.7</h2>
