Complementary angles are angles that sum up to 90 degrees. If ∠LKJ is measured, you can find ∠GHI by subtracting the measure of ∠LKJ from 90 degrees.
However, since the measure of ∠LKJ is not provided in your question, I cannot determine the exact measure of ∠GHI among the options given. If you have the measure of ∠LKJ, please provide it so I can help you calculate the measure of ∠GHI.
For now, you can use this formula: \[ \text{Measure of \(\angle GHI\)} = 90^\circ - \text{Measure of \(\angle LJK\)} \] Check to see if any of the provided options make sense, based on the angle of ∠LKJ. If, for example, ∠LKJ was 34°, then ∠GHI would be 56° (since 90° - 34° = 56°).
