How do I find the x to this picture

Step-by-step explanation:

This is a right triangle and we are looking for a missing side. We can use the Pythagorean Theorem to find x.

where a and b are the legs and c is the hypotenuse.

In this triangle, the legs are 28 and 13 because they make up the right right angle. x is the hypotenuse because it is opposite the right angle.

Substitute the values in.

Solve the exponents.

Add the two numbers.

We want to solve for x, which means we must isolate it.

The x is being squared. The inverse of a square is the square root, so take the square root of both sides of the equation.

Let's round to the nearest hundredth. The 7 in the thousandth place tells us to round the 8 to a 9.

x is about 30.9

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
