A window has the shape of a square of side length 60 cm surmounted
by a segment of a circle of radius 50 cm. The circle segment is less
than a semicircle. What is the maximum height, in centimeters, of the window?

Make a sketch on your own.
In the sketch, the center of the circle is somewhere inside the square.
Connect the center with the square's upper corners by straight lines.
Draw a perpendicular from the center to the mid-point of the upper horizontal
side of the square.
In the sketch, you have a right-angled triangle.
Its hypotenuse is 50 cm. One of its leg (horizontal) is 60/2 = 30 cm long.
Hence, according to the Pythagorean theorem, its other leg (vertical) has
the length of = 40 cm.
It means that the maximum height of the window is 60 cm + 60 cm + (50-40) cm = 130 cm.
ANSWER. The maximum height of the window is 130 centimeters.
Solved.
