Simplify your answer and write it as a proper fraction, improper fraction, or whole number.
tan(J)=

Answer 1

The side lengths 28, 45, 53 form a right triangle (28^2 + 45^2 = 53^2), so the right angle is at K (hypotenuse IJ = 53). For angle J the opposite side is KI = 45 and the adjacent side is JK = 28.

tan(J) = 45/28.
