Answer:
<h2><u>Answer</u><u> </u><u>:</u><u>-</u></h2>
Here,
At first we know that parallel line cut transversal lines. They make them in a proportion.
h/10 = 9/13
h = 10 × 9/13
h = 90/13
h = 6.92

<u><em /></u>Subtracting a negative number really means to add it
Here's addition:
(1) + (1) = 2
(1) + (-1) = 0
(-1) + (-1) = -2
(-1) + (1) = 0
Here's subtraction:
(1) - (1) = (1) + (-1) =0
(1) - (-1) = (1) + (1) = 2
(-1) - (-1) = (-1) + (1) = 0
(-1) - (1) = (-1) + (-1) = -2
Here's your problem specifically:
(5/10) - (-8/10)
(5/10) + (8/10)
*since they have the same denominator, that stays the same, and you only have to add up numerators
(5 + 8)/10
13/10
<u><em>answer is 13/10 . . . it's positive</em></u>
