Perpendicular means the slopes are opposite inverse of each other
If line a is slope 2, the perpendicular line to Line a would have a slope - 1/2
Difference in y over difference in x gives slope. If they are opposite inverse values the lines are perpendicular. ( in this case the answer is true.)

Consider triangle GHJ.

bulgar [2K]

we know that

<u>Applying the Pythagorean Theorem</u>

$JG^{2} =HJ^{2}+HG^{2}$

solve for HJ

$HJ^{2}=JG^{2}-HG^{2}$

in this problem we have

$JG=10\ units\\ HG= 5\ units$

Substitute the values in the formula above

$HJ^{2}=10^{2}-5^{2}$

$HJ^{2}=100-25$

$HJ^{2}=75$

$HJ=\sqrt{75}=5\sqrt{3} \ units$

therefore

<u>the answer is the option</u>

B. 5 sq. root 3 units
