Answer:
about 15.6cm.
Step-by-step explanation:
I got my answer of 15.6cm because I did the Pythagorean theorem.
a^2+b^2=c^2
The values of "a" and "b" are the legs of the triangle, and the value of "c" is the hypotenuse. So, the equation with the values given is 9^2+b^2=18^2.
Simplified is 81+b^2=324. Next, you have to subtracted 81 on each side, so you have "b" by itself. b^2=243. Now, I know that b^2= 243. Next, find the square root of 243. The square root of 243 is 15.58845727. This value rounded to the nearest tenth is about 15.6.
In conclusion, the measure of the other leg is about 15.6cm.

You have to match the letters to the numbers.
0=P, 5=I, 8=A, 2=L, 3=C, 4=E
Once you have all that info you can figure out your answer by writing LACE and trying to match the numbers to those four letters.
Hope that helps :)
