To find the value of x, we will have to set the perimeters equal.
(2x+4)*4 would be P for the square and (2x+8)*3 would be P for the triangle.
We have to set these equal and solve for x.
(2x+4)*4=(2x+8)*3
8X+16=6x+24
-6x -16 -6x -16
2x=8
x=4
Now we plug x=4 in for each perimeter.
Square: 2(4)+5=13
Triangle: 2(4)+8=16

Find the value of x in a triangle with one side 11 and 1 angle being 28

Andre45 [30]

Answer:

C: 12.5

Step-by-step explanation:

The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.

First we can set up our equation

$cos28=\frac{11}{x}$

Next we can solve for x by multiplying by x and dividing by $cos 28$

$x=\frac{11}{cos28}\\\\x=12.458\\\\x=12.5$
