B. 25, acute
You can see it’s acute. 160 would be obtuse
You can write 15,409 like this 10000+5000+400+9 and like this fifteen thousand-four hundred nine
65,000
Pretty sure bc 1 isn't big enough to move the 5 up a number
We need to find the percentage of the extra feet that she measured, so first we have to find out how much that is. We can do this by simply subtracting:
4.27 - 4 = 0.27
Now we can set up a proportion to find the percentage.

Solve for x
0.27 x 100 = 27
27/4 = 6.75
The answer is
6.75% :)
