Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.

Remember: SOH-CAH-TOA

Looking from angle I, we know the opposite side and the hypotenuse. Therefore, we should use sine.

sin(I) = \frac{\sqrt{39}}{\sqrt{51}}

To solve, you can use your calculator and the inverse sine function (sin^-1).

I = sin^-1(\frac{\sqrt{39}}{\sqrt{51}})

I = 61 degrees

Hope this helps!
