Answer: The sine of ∠I is represented by the ratio 63:65
Step-by-step explanation:
First, let's draw the triangle (see the picture below.)
Remember SOHCAHTOA? We need to use it here.
-sin = opposite/hypotenuse
-cos = adjacent/hypotenuse
-tan = opposite/adjacent.
Assuming that ∠I is Ф, we can see that its opposite side is equal to 63 and the hypotenuse is 65. Therefore,
[tex]sin = \frac{63}{65}[/tex]
