Answer this one for me thanks ppppp

Answer:

16.6 units

Step-by-step explanation:

Hi there!

We can use the Pythagorean theorem to help us solve this problem: $a^2+b^2=c^2$ where c is the longest side of a right triangle (the hypotenuse) and a and b are the other two sides

It's safe to assume that x is the longest side in this triangle, making it the c value. Plug 14 and 9 into the equation as a and b and solve for x:

$14^2+9^2=x^2\\196+81=x^2\\277=x^2\\x=16.6$

Therefore, the value of x is 16.6 units when rounded to the nearest tenth.

I hope this helps!

The sum of the measures of the interior angles of a convex polygon is 3960°.

scZoUnD [109]

Step-by-step explanation:

The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
