What fraction would you use to find 66.66% of 72?

I don't think you use a fraction. You multiply .6666 by 72 which equals 47.9952 or rounded 48. :)

What is the length of AC

solmaris [256]

Answer:

The answer is the option D $AC=126\ units$

Step-by-step explanation:

we know that

The triangles EDC and ABC are similar

then

The ratio of their corresponding sides is equal

$\frac{EC}{CA}=\frac{DE}{AB}$

substitute

$\frac{x}{140-x}=\frac{9}{81}$

solve for x

$9x=140-x\\9x+x=140\\x=140/10\\x=14\ units$

Find the length of AC

$AC=140-x=140-14=126\ units$
