Find the length of LA Triangle proportionality
2 answers:
Answer:
15
Step-by-step explanation:
4 x __ = 12
the blank would be 3, once you did it on one side you have to do it on the other side too
5 x 3 = 15
Another way you can do it is by...
=
solve for x (cross multiply)
Answer:
15
Step-by-step explanation:
CO : CL = OR : LA
* substitute the side letters with the given side lengths *
( let AL = x )
4 : 5 = 12 : x or
now we solve for x by cross multiplying
4 * x = 4x
12 * 5 = 60
now we have 4x = 60
step 2 divide each side by 4
4x / 4 = x
60 / 4 = 15
we're left with x = 15
hence LA = 15
