Because IJ is equal to 15, and IK is equal to 8, all you have to do is to add those two numbers up. IJ and IK are two segments within the segment IK, and they make up the segment IK, so therefore all you need to do is to add IJ and JK.
The answer is D. 23
Hope this answer helped!! Feel free to post more questions if needed!
With the ratio, since Zeona has 36 cards, Kyle must have 54. If they each sold half, Kyle would have 27 and Zeona would have 18. So, the ratio would still be 3:2.
