Find y when X=15 , if y =6 when x=30

3

Step-by-step explanation:

One way is that 30/6 should equal to 15/k. K is the variable. You can do 30/6(5) which means that whatever k equals, the final answer should be 5. So you can do 15/3, which will equal 5 too. So you'll know that they're identical which means that it is correct.

Another way is to see that 15 is half of 30, so it means the answer should be half of 6. 3!

Hope this helped.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
