Question

I have a feeling the answer might be 1:2 BUT I AM PROBABLY VERY WRONG

Answer 1

Yes you are wrong

Answer 2

Check the two sides being compared, in this case, XZ should be compared to AC

Answer 3

10:15 so which option would suit you?

Answer 4

have the corresponding side over each other
YZ/BC = XZ/AC
30/BC = 10/15
10BC = 450
BC = 45

Thus the ratio is
30/45 = 10/15
2/3 = 2/3

so it would be 2/3

Answer 5

Btw, being @dehydrated is probably not going to help you with Math much... Stay Hydrated, Stay Healthy :D :). Cheers.

Answer 7

@mecharv very true statement
