Find the unknown side length x write your answer in simplest radical form

Sauron [17]

Answer:

(B) $4\sqrt{37}$

Step-by-step explanation:

First, we determine the height of the triangle which we label as y.

Using Pythagoras Theorem.

$25^2=7^2+y^2\\y^2=25^2-7^2\\y^2=576\\y=\sqrt{576}\\y=24$

In the smaller right triangle with hypotenuse, x

Base = 7-3 =4 Units

Height, y= 24 Units

Therefore, applying Pythagoras Theorem.:

$x^2=24^2+4^2\\x^2=592\\x=\sqrt{592}\\ x=4\sqrt{37}$

Elina [12.6K]

The circle with center (h, k) and radius r has equation
.. (x -h)^2 +(y -k)^2 = r^2

You have
.. h = 2
.. k = 0
.. r = √5

The center is (h, k) = (2, 0).

Identify the percent of change as an increase or decrease 38 staples to 55 staples find the percent of change round to the neare

erik [133]

Answer:

The percent of change is 44.7%

Step-by-step explanation:

Given that:

38 staples to 55 staples

As the number of staples are increased, therefore, the percent will also increase.

Difference = 55 - 38 = 17 staples

Percent of change = $\frac{Difference}{Original\ number}*100$

Percent of change = $\frac{17}{38}*100$

Percent of change = 0.447*100

Percent of change = 44.7%

Hence,

The percent of change is 44.7%
