Question

In ΔIJK, the measure of ∠K=90°, KI = 3.8 feet, and JK = 6.7 feet. Find the measure of ∠I to the nearest degree.

Answer 1

Answer:

60

Step-by-step explanation:tanI=

3.8

6.7

​  

 

\tan I = \frac{6.7}{3.8}

tanI=  

3.8

6.7

​  

 

I=\tan^{-1}(\frac{6.7}{3.8})

I=tan

I=60.44\approx 60^{\circ}

I=60.44≈60
