Pythagorean theorem
the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse

Answer:
132
Step-by-step explanation:
the top rectangle is 28
the middle rectangle is 56
each of the triangles are 24
48+28+56
X + 19 + 7x + 9 = 180
8x + 28 = 180
8x = 180 - 28
8x = 152
X = 152 : 8
X = 19
