What is the value of x? enter your answer in the box.

Use the Pythagorean theorem.

a² + b² = c²

c is the hypotenuse which is 13.

a and b are either x and 12, so i put a as x and 12 as b

x² + 12² = 13²

x² + 144 = 169

x² = 25

x = 5

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
