Answer and Explanation:
Since this is a 30-60-90 triangle, you can use the ratio of side lengths specific to this type of triangle:
x = 4√(2)
y = 2(4) = 8
because where 4 = T,
x = T√2 and y = 2T
so again:
Emily measured the height of a dresser as 4.27 feet, but the actual height was 4 feet. What is the percentage of error in Emily’
1 answer:
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% :)
