Scoliosis is a common disease of the spine, where the spine is not straight, but forms an "S" or "C" shape, while viewing a patient from the front. One of the most widely used indicators of scoliosis is a measurement of the Cobb angle (a), as it is a quantitative measure of the spinal curvature. The Cobb angle is calculated directly on X-ray radiographs of the spine (see photo). To determine the Cobb angle, the health professional must decide which two vertebrae are at each end of the deformity. They correspond to the two vertebrae that are rotated the most from a vertical position. In the sample X-ray below, these are shown with green arrows. Lines are then drawn (solid blue) along the endplates of these vertebrae until they intersect as shown, forming the Cobb angle a. In this example, an isosceles triangle is formed, where the two equivalent sides have a length h, and the third side has a length of 0.65h. If the angle 0 in the figure has a value of 38°, what is the value of the Cobb angle, a? Oo 08 h aillard,
