Final answer:
To find the measure of angle HFJ, subtract the given angle from 180°.
Step-by-step explanation:
To find the measure of Κ/HFJ, we can use the fact that tangent lines are perpendicular to the radius drawn to the point of tangency. In this case, GHJ is a right triangle, with HG as the hypotenuse and HF as one of the legs. Since the tangent and radius are perpendicular, we know that measure of ΚGHJ = 90°.
The sum of the angles in a triangle is 180°, so we can find measure of ΚHFJ by subtracting the given angle from 180°. Therefore, m/HFJ = 180° - m/HGJ = 180° - 27° = 153°.
