The semicircular shape of a protractor is drawn with measurements. Four rays are superimposed on the protractor. The markings on a protractor range from 0 to 180 degrees from left to right on the outer scale. The markings on a protractor range from 0 to 180 degrees from right to left on the inner scale. Radial lines are drawn from the origin at the center of the baseline outward to form the angles marked on both the inner and outer scales. The origin is labeled as H. A ray labeled H G extends from point H along 22 degrees on the outer scale. A second ray labeled H I extends from point H along 49 degrees on the outer scale. The third ray is labeled H J extends from point H along 138 degrees of the outer scale. The fourth ray labeled H K extends from point H along 176 degrees on the outer scale. The angles formed by the four rays are marked with arcs.

The measure of angle GHI can be determined by measuring the angle between the rays H G and H I on the protractor.
From the given information, we know that ray H G extends along 22 degrees on the outer scale and ray H I extends along 49 degrees on the outer scale.
To measure angle GHI, we need to find the difference between the measures of H I and H G. Therefore, the measure of angle GHI is 49° - 22° = 27°.
So, the correct answer is 27°.
