Answer:
she ate 3/20 of the pie
Explanation:
lets say there are 10 slices.
if she ate 1 slice, then darryl ate 2, then Emily ate 3. That is only 5 total slices.
So what if she ate 2? Darryl ate 4, Emily ate 6. That still doesn't work
But if she ate 1.5 slices, then darryl ate 3, then Emily ate 5.5
1.5+5.5=7
7+3=10
so she ate 1.5 slices out of ten. But 1.5/10 cant be a fraction, so you can make it 15/100 and then simplify it 3/20. :)

Answer:
10
Step-by-step explanation:
So it's a 30-60-90 triangle, which you can either find with trig or if you remember this rule you can find it quick. In the pic n is 5, so to find x you just follow the rule and multiple 5 times 2, which is 10. Then the other side of the triangle would be 
. This rule applies to any 30-60-90 triangle.
