The perimeter of a polygon is the sum of the lengths of all its sides. A rectangle has 4 sides, and opposite sides are congruent, so 2 sides have length x + 5, and 2 sides have length 11. Add all the lengths and set the sum equal to 50. Then solve the equation for x.
x + 5 + x + 5 + 11 + 11 = 50
2x + 32 = 50
2x = 18
x = 9
Answer: x = 9
Let's say that the hypotenuse is length 1.
In a 45 45 90 triangle, the legs are equal to the hypotenuse * (1 / [sq rt (2)])
So if the hypotenuse =1, the legs equal 1 /

Answer:
y = cos(x)
Step-by-step explanation:
This graph of the cosine function has no shifting or scaling. It is a plain cosine function:
y = cos(x)

<em>Additional comment</em>
It will be worth your time to learn to recognize the sine and cosine functions. They have a maximum of +1, a minimum of -1 and a period (horizontal distance between corresponding points) of 2π. The sine function is symmetrical about the origin. The cosine function is symmetrical about the y-axis. The maximum slope (near the zero-crossings) is 1.
