In triangle IJK, the measure of angle K is 90, IK= 39, JI = 89 and KJ= 80. What ratio represents the sine of angle I?

Answer:
80 / 89
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, the following data were obtained:
<I = θ
Hypothenus = 89
Opposite = 80
Sine <I =?
Sine ratio of <I can be obtained as follow:
Sine θ = Opposite / Hypothenus
Sine <I = 80 / 89
Thus, the ratio of sine <I is 80 / 89
