The answer is A.

Explanation:

Since this is a right triangle you can use The formula: leg squared plus leg squared = hypotenuse squared

So lets square the hypotenuse and first leg
And you get 85 hypotenuse and 49 leg

So just subtract 49 from 85 to get the other leg squares

You get 36 so now just square root it

Square root of 36 is 6

So the best answer is 6

Hope this helps some.

Answer:

The other diagonal measures 21m

Step-by-step explanation:

In this question, we are tasked with calculating the length of the second diagonal of as Rhombus given the measure of the surface area of the rhombus and the length of the other diagonal

Mathematically, for a rhombus having two diagonals $d_{1}$ and $d_{2}$ , the area of the rhombus can be calculated mathematically using the formula below;
