see the attached figure to better understand the problem
we have that

Step 1
<u>Find the value of AC</u>
we know that
in the right triangle ABC

substitute the values in the formula

Step 2
<u>Find the value of BC</u>
we know that
in the right triangle ABC
Applying the Pythagorean Theorem

substitute the values

Step 3
<u>Find the value of BD</u>
we know that
in the right triangle BCD
Applying the Pythagorean Theorem

substitute the values


therefore
<u>the answer is</u>
the length of BD is 11.93 units
Up and down up and down up and down
Writing an equation would be most helpful, but depending on the situation drawing a diagram or reading a table could work better.
7 1/3
I think this is it, i would like for u to get a second opinion.
It equals 5/6 And the decimal form is 0.8333 and so on
