Homework 1:Pythagorean Theorem and it’s Converse
Find The Value of X

The figure gives a dimension for the hypotenuse of 19
the height is given as 17, using the Pythagorean theorem we can find the base of the triangle:
19^2 = 17^2 + base^2
Simplify:
361 = 289 + base^2
Subtract 289 from both sides:
72 = base^2
Take the square root of both sides:
Base = 8.49 Round to 8.5
There are two identical triangles on each sides, so 8.5 x 2 = 17
The length of the two triangle bases is 17
The total base of the object is 31, so the length of the rectangular part in the middle would be 31 - 17 = 14
And X would be the same length as the bottom rectangle.
Therefore x = 14
Answer:
x = 14
Step-by-step explanation:
Inside the trapezoid, there are two right triangles, with a hypotenuse of 19 and a leg of 17. The other leg can be computed with the help of the pythagorean theorem as follows:
[tex] {c}^{2} = {a}^{2} + {b}^{2} \\ {19}^{2} = {17}^{2} + {b}^{2} \\ 361 = 289 + {b}^{2} \\ 361 - 289 = {b}^{2} \\ 72 = {b}^{2} \\ \sqrt{72} = {b}^{2} \\ 8.5 = b[/tex]
Now, we can calculate the value of x, as follow;
8.5 + x + 8.5 = 31
17 + x = 31
x = 31 - 17
x = 14
