In ΔIJK, the measure of ∠K=90°, KI = 5.3 feet, and JK = 2.1 feet. Find the measure of ∠I to the nearest tenth of a degree. I

is the correct answer.

Step-by-step explanation:

Please refer to the attached figure.

is shown with the following measurements:

Side KI = 5.3 ft

Side JK = 2.1 ft

To find : = ?

Using trigonometric identity for tangent of an angle:

Here

Perpendicular is side JK.

Base is side KI.

Putting the values in above formula:

Hence, is the correct answer.
