In AIJK, the measure of ZK=90°, KI = 5.3 feet, and JK = 2.1 feet. Find the measure of
ZI to the nearest tenth of a degree.

Answer 1

22°

Explanation:

to get the value of angle I, use the formula: x tan⁻¹Ф = h

where: x = 5.3

h = 2.1

Ф = ?

plugin values into the formula;

5.3 tan⁻¹Ф = 2.1

tan⁻¹Ф = 2.1

5.3

≈ 22°

Answer 2

< i = 21.6 degrees

Explanation:

Side KI = 5.3 ft

Side JK = 2.1 ft

To find : = ?
